Community resilience is the capacity of individuals and households within a community to absorb the external stresses of a disaster. To measure this, the Census Bureau produced the 2019 Community Resilience Estimates (CRE). To provide context to the estimates and add to the discussion of equity, the CRE program has created the Community Resilience Estimates Equity Supplement or CRE for Equity. The CRE for Equity dataset provides information about the nation, states, counties, and census tracts from three different data sources. These sources include the Community Resilience Estimates, the American Community Survey, and the Census Bureau’s Planning Database. Providing all this information in one dataset allows users quick access to the data on a variety of topics concerning social vulnerability and equity.

The Community Resilience Estimates track how at-risk every neighborhood in the United States is to the impacts of a disaster. The Community Resilience Estimates use American Community Survey microdata and Population Estimates Program data to measure the capacity of individuals and households to absorb the external stresses of the impacts of a disaster.

The table State shape file is part of the dataset Census Bureau Community Resilience Estimates (CRE) datasets, available at https://redivis.com/datasets/45vc-a00v3cwcb. It contains 51 rows across 1 variables.

Local planners, policy makers, public health officials, emergency managers, and community stakeholders need a variety of estimates to help assess the potential resiliency and vulnerabilities of communities and their constituent populations to help prepare and plan mitigation, recovery, and response strategies. Community Resilience Estimates (CRE) focuses on developing a tool to identify socio-economic vulnerabilities within populations. The 2022 Community Resilience Estimates (CRE) are produced using information on individuals and households from the 2022 American Community Survey (ACS) and the Census Bureau’s Population Estimates Program (PEP). The CRE uses small area modeling techniques that can be used for a broad range of disaster related events (hurricanes, tornadoes, floods, economic shocks, etc.) to identify population concentrations likely to be relatively more impacted by and have greater difficulties overcoming disasters. The end result is a data product which measures vulnerability more accurately and timely. Data:The ACS is a nationally representative survey with data on the characteristics of the U.S. population. The sample is selected from all counties and county-equivalents and has a sample size of about 3.5 million housing units each year. It is the premier source for timely and detailed population and housing information about our nation and its communities. We also use auxiliary data from the PEP, the Census Bureau’s program that produces and publishes estimates of the population living at a given time within a geographic entity in the U.S. and Puerto Rico. We use population data from the PEP by age group, race and ethnicity, and sex. Since the PEP does not go down to the census tract level, the CRE uses the Public Law 94-171 summary files (PL94) and Demographic Housing Characteristics File (DHC) tables from the 2020 Decennial Census to help produce the population base estimates. Once the weighted estimates are tabulated, small area modeling techniques are used to create the estimates for the CRE. Components of Social Vulnerability (SV): Resilience to a disaster is partly determined by the components of social vulnerability exhibited within a community’s population. To measure these components and construct the community resilience estimates, we designed population estimates based on individual- and household-level components of social vulnerability. These components are binary indicators or variables that add up to a maximum of 10 possible components using data from the ACS. The specific ACS-defined measures we use are as follows: Components of Social Vulnerability (SV) for Households (HH) and Individuals (I):SV 1: Income-to-Poverty Ratio (IPR) < 130 percent (HH). SV 2: Single or zero caregiver household - only one or no individuals living in the household who are 18-64 (HH). SV 3: Unit-level crowding with >= 0.75 persons per room (HH). SV 4: Communication barrier defined as either: Limited English-speaking households1 (HH) orNo one in the household over the age of 16 with a high school diploma (HH). SV 5: No one in the household is employed full-time, year-round. The flag is not applied if all residents of the household are aged 65 years or older (HH). SV 6: Disability posing constraint to significant life activity. Persons who report having any one of the six disability types (I): hearing difficulty, vision difficulty, cognitive difficulty, ambulatory difficulty, self-care difficulty, and independent living difficulty. SV 7: No health insurance coverage (I). SV 8: Being aged 65 years or older (I). SV 9: No vehicle access (HH). SV 10: Households without broadband internet access (HH). Each individual is assigned a 0 or 1 for each of the components based upon their individual or household attributes listed above. It is important to note that SV 4 is not double flagged. An individual will be assigned a 1, if either of the characteristics is true for their household. For example, if a household is linguistically isolated and no one over the age of 16 has attained a high school diploma or more education, the household members are only flagged once. The result is an index that produces aggregate-level (tract, county, and state) small area estimates: the CRE. The CRE provide an estimate for the number of people with a specific number of social vulnerabilities. In its current data file layout form, the estimates are categorized into three groups: zero , one-two, or three plus social vulnerability components. Differences with CRE 2021:The number of census tracts have increased from 84,414 in CRE 2021 to 84,415 in CRE 2022. This is due to the boundary changes in Connecticut implemented in 2022 census data products. To accommodate the boundary change, Connecticut also now has nine planning regions instead of eight counties in CRE 2022.To avoid confusion, the modeled rates are now set to equal zero in CRE 2022 for geographic areas with zero population in universe. To improve the population base estimates, CRE 2022 uses more detailed decennial estimates from the 2020 DHC in addition to PL94, whereas CRE 2021 just used PL94 due to availability at the time.

Abstract

The 2019 Community Resilience Estimates (CRE) are produced using information on individuals and households from the 2019 American Community Survey (ACS) and the Census Bureau’s Population Estimates Program (PEP). Local planners, policy makers, public health officials, and community stakeholders can use the estimates as one tool to help assess the potential resiliency of communities and plan mitigation and recovery strategies. The CRE uses small area modeling techniques. These techniques are flexible and can easily be modified for a broad range of uses (hurricanes, tornadoes, floods, economic recovery etc.).

The table is consisted of geographic infomation including state county and tract, and variables indcating risk factors. The CRE groups the population estimates into three categories: zero risk factors, one-two risk factors, and three plus risk factors. The data file includes the population estimate, estimate margin of error, rate, and rate margin of error for each of the three categories.

The table Counties shape file is part of the dataset Census Bureau Community Resilience Estimates (CRE) datasets, available at https://redivis.com/datasets/45vc-a00v3cwcb. It contains 3142 rows across 1 variables.

"Components of Social Vulnerability" refers to the categories of social vulnerability out of a possible 10 variables (e.g., poverty status, age 65+, unemployment, etc.), where 0 components is considered "low," 1-2 components is considered "moderate, and 3 or more components is considered is "high.".POPUNI refers to the population universe, which includes all adults except those in correctional or juvenile facilities and college dorms..For the variables ending in PF_PR and PF_US, the given rate is compared to the PR rate and U.S. rate, respectively. For example, PRED0_PF_PR denotes whether the estimated percentage of individuals with zero components of social vulnerability is significantly different than the PR rate. These variables use the following values: -999 = Not applicable; -1 = Lower; 0 = Not statistically different; and 1 = Higher.

The table Community Resilience Estimates 2019 is part of the dataset Census Bureau Community Resilience Estimates (CRE) datasets, available at https://redivis.com/datasets/45vc-a00v3cwcb. It contains 76250 rows across 19 variables.

The data have the number of people and percent of population within a census tract who have 0, 1-2, or 3 or more CRE components. Margins of error for each are included.The CRE components are:Income-to-Poverty ratio more than 130%Single or zero caregiver householdUnit-level crowding with >= 0.75 persons per roomCommunication Barrier:No one in the household speaks English "very well"No one in the household has received a high school diplomaNo one in the household is employed fill-time, year-roundDisabilityNo health insurance coverageAged 65 years or oldNo vehicle accessHouseholds without broadband internet accessThe Community Resilience Estimates were first released as an experimental data product in mid-2020. During the experimental data product phase, the Community Resilience Estimates team received feedback from subject-matter-experts and several Federal agencies on what indicators need to be included in an official release. The indicators were suggested based on research, theory, and need.

The table Community Resilience Estimates 2018 is part of the dataset Census Bureau Community Resilience Estimates (CRE) datasets, available at https://redivis.com/datasets/45vc-a00v3cwcb. It contains 76249 rows across 21 variables.

Community Resilience Estimates (arcgis.com)

This filtered view includes census tracts in Maricopa County only. Published by the US Census Bureau, the Community Resilience Estimates (CRE) for Heat measures social vulnerability specifically in the context of extreme heat exposure. See the "Source Link" below for more information.

In collaboration with Arizona State University’s Knowledge Exchange for Resilience, the CRE for Heat are produced using information on individuals and households from the American Community Survey (ACS) and the Census Bureau’s Population Estimates Program (PEP).

Community resilience describes the capacity of individuals and households within a community to absorb a disaster’s external stressors. The standard Community Resilience Estimates (CRE) measures a community’s social vulnerability to natural disasters. However, the social vulnerabilities to extreme heat exposure differ from other natural disasters. As a result, the CRE Team created a new set of estimates called the Community Resilience Estimates for Heat (CRE for Heat).The CRE for Heat is an experimental data product from the U.S. Census Bureau. Experimental data products are innovative statistical products created using new data sources or methodologies that benefit data users in the absence of other relevant products. The Census Bureau is seeking feedback from data users and stakeholders on the quality and usefulness of these new products.In collaboration with Arizona State University’s Knowledge Exchange for Resilience (KER), the CRE Team produced the 2022 CRE for Heat using data on individuals and households. The data sources include the 2022 American Community Survey (ACS), the Census Bureau’s Population Estimates Program (PEP), and the 2020 Census. Based on feedback from data users, the CRE for Heat contains a new component of social vulnerability, “Households that potentially lack air conditioning”. This component of social vulnerability was created using data from the 2021 American Housing Survey, machine learning techniques, and auxiliary data. More information about this is found in the CRE for Heat Quick Guide.Local planners, policymakers, public health officials, and community stakeholders can use the CRE for Heat to assess their community’s vulnerability to extreme heat and plan cooling and intervention strategies. WHAT’S NEWComponents of Social Vulnerability (SV)The CRE adjusted terminology from “risk factors” to “components of social vulnerability” after discussions with stakeholders such as emergency managers and urban planners. In these fields, “risk” refers to the likelihood a disaster or event will occur. “Vulnerabilities” refer to the conditions people experience which may compound the impact of a disaster.The CRE Program is committed to providing a data product that is understandable and meets the needs of its users. To better explain the purpose of the estimates and how they were developed, the language was adjusted.“Components” highlights the combination of factors that define social vulnerability. “Social vulnerability” refers to the characteristics that could impede a community’s ability to deal with disasters and external stressors. The results of this assessment form the basis of a community’s Community Resilience Estimate.Extreme Heat ExposureThe CRE for Heat 2022 estimates contain an additional measure of exposure to extreme heat (PRED3EXP). Not all socially vulnerable communities are equally exposed to extreme heat. Pairing the CRE for Heat estimates with heat exposure data provides a more comprehensive look at social vulnerability to heat. In the 2022 CRE for Heat dataset, an area is considered exposed to extreme heat if it meets one of two criteria. The two heat exposure criteria are:Areas where the maximum air temperature has reached or exceeded 90 degrees Fahrenheit for two or more days in a row during 2022.Areas where estimated wet bulb temperature has reached or exceeded 80 degrees at any time during 2022.On the county and tract level files, these exposure variables are available as LONG_90_DAY and MAX_WBT.On the state and national file, the exposure variable, PRED3EXP_E, measures the estimated number of individuals with three plus components of social vulnerability who also live in a county exposed to an extreme heat event in 2022. Similarly, PREDEXP_PE, measures the rate of individuals with three plus components of social vulnerability who also live in a county exposed to an extreme heat event in 2022. These variables, and their accompanying margins of error, are available on the national and state files.Components of Social VulnerabilityComponents of Social Vulnerability (SV) for Households (HH) and Individuals (I)SV 1: Financial hardship defined as: Income-to-Poverty Ratio (IPR) < 130 percent (HH) or50% < for housing/rental costs (HH). SV 2: Single or zero caregiver household - only one or no individuals living in the household who are 18-64 (HH).SV 3: Housing quality described as:Unit-level crowding with > 0.75 persons per room (HH) orLive in mobile home, boat, RV, Van, or other (HH). SV 4: Communication barrier defined as either:Limited English-speaking households (HH) or No one in the household has a high school diploma (HH). SV 5: No one in the household is employed full-time, year-round. The flag is not applied if all residents of the household are aged 65 years or older (HH).SV 6: Disability posing constraint to significant life activity. Persons who report having any one of the six disability types (I): hearing difficulty, vision difficulty, cognitive difficulty, ambulatory difficulty, self-care difficulty, and independent living difficulty. SV 7: No health insurance coverage (I). SV 8: Being aged 65 years or older (I). SV 9: Transportation exposure described as:No vehicle access (HH) orWork commuting methods with increased exposure to heat (e.g., public transportation, bicycle, walking) (I). SV 10: Households without broadband Internet access (HH). SV 11: Households that potentially lack air conditioning (HH).

The Community Resilience Estimates program provides an easily understood metric for how at-risk every neighborhood in the United States is to the impacts of disasters.This ready-to-use layer can be used within ArcGIS Pro, ArcGIS Online, its configurable apps, dashboards, Story Maps, custom apps, and mobile apps. Data can also be exported for offline workflows. Please cite the Census, CRE, and ACS when using this data.About: The 2021 Community Resilience Estimates, Equity Supplement or “CRE for Equity” consists of 4 data files that provide estimates for the nation, states, counties, and tracts. CRE refers to the Community Resilience Estimates, which provides an easily understood metric for how at-risk every neighborhood in the United States is to the impacts of disasters. The equity portion refers to data from the American Community Survey that give social context to the CRE estimates and add to the discussion of equity. The datasets combine data from the 2021 Community Resilience Estimates, 2017-2021 American Community Survey 5-year estimates, and the 2021 Census Planning Database. Each unique geographic observation will have a single row of data. The CRE groups the population estimates into three categories: zero risk factors, one-two risk factors, and three plus risk factors. The data file includes the population estimate, estimate margin of error, percentage, and percentage margin of error. A flag denoting whether an estimate is statistically different has also been provided for each of the three categories for the CRE estimates. Data from the American Community Survey have also been provided as part of this dataset. Whether the variable is an estimate, percentage, or margin of error, this is denoted in the variable names.Risk factors include:Income to Poverty RatioSingle or Zero Caregiver HouseholdCrowdingCommunication BarrierHouseholds without Full-time, Year-round EmploymentDisabilityNo Health InsuranceAge 65+No Vehicle AccessNo Broadband Internet AccessField NamingThe numeric population estimates are denoted by an “E” at the end of the variable name. The margins of error for these estimates have a “M”. The fields for percentages and the accompanying margins of error are denoted with “PE” and “PM”. Variable names that end in “F” note that they are a flag variable. These flag variables denote if an estimate is statistically different from the national average. Data Note from the Census:Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. Some estimates are not available from the American Community Survey because some estimates are suppressed or controlled. When this occurs, the variable field is filled with an “Annotation value” which denotes why an estimate is not available. Additional information can be found on the Census Bureau’s website. For more information on sampling and estimation methods, confidentiality protection, and sampling and nonsampling errors in the ACS, visit https://www.census.gov/programs-surveys/acs/technical-documentation/code-lists.html Data Processing Notes:Boundaries come from the Cartographic Boundaries via US Census TIGER geodatabases. Boundaries are updated at the same time as the data updates, and the boundary vintage appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines clipped for cartographic purposes. For state and county boundaries, the water and coastlines are derived from the coastlines of the 500k TIGER Cartographic Boundary Shapefiles. The original AWATER and ALAND fields are still available as attributes within the data table (units are square meters). This dataset does not contain values for Puerto Rico or Island Areas at any level of geography.

The Biden-Harris administration announced the launch of a new Voluntary Community-Driven Relocation program, led by the Department of the Interior, to assist Tribal communities severely impacted by environmental threats. Through investments from President Biden’s Bipartisan Infrastructure Law and Inflation Reduction Act, the Department is committing $115 million for 11 severely impacted Tribes to advance relocation efforts and adaptation planning. Additional support for relocation will be provided by the Federal Emergency Management Administration (FEMA) and the Denali Commission. Alaska communities located along coastlines and tidally influenced rivers are vulnerable to coastal erosion. These communities face advanced planning decisions, such as implementing shore protection or moving infrastructure. This work aims to provide quantitative erosion exposure data to Alaskans that can be combined with local knowledge and evidence for developing hazard mitigation plans and strategies to address erosion. DGGS Report of Investigation 2021-3, Erosion exposure assessment of infrastructure in Alaska coastal communities, provides estimated erosion exposure for 48 communities from the Bering to the Beaufort seas. The Division of Geological & Geophysical Surveys conducted a shoreline change assessment to forecast 20-, 40-, and 60-year erosion estimates using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018), and estimated the replacement cost of infrastructure in the forecast area. The geodatabase includes mean erosion forecasts and maximum uncertainties for 38 communities along with infrastructure locations and classification derived from Alaska Division of Community & Regional Affairs digital mapping products (DCRA, 2021) for 44 communities. All files are available from the DGGS website: https://doi.org/10.14509/30672. The sea level rise (SLR) coastal inundation layers were created using existing federal products: the (1) NOAA Coastal Digital Elevation Models (DEMs) and (2) 2022 Interagency Sea Level Rise Technical Report Data Files. The DEMs for the Continental United States (CONUS) are provided in North American Vertical Datum 1988 (NAVD 88) and were converted to Mean Higher High Water (MHHW) using the NOAA VDatum conversion surfaces; the elevation values are in meters (m). The NOAA Scenarios of Future Mean Sea Level are provided in centimeters (cm). The MHHW DEMs for CONUS were merged and converted to cm and Scenarios of Future Mean Sea Level were subtracted from the merged DEM. Values below 0 represent areas that are below sea level and are “remapped” to 1, all values above 0 are remapped to “No Data”, creating a map that shows only areas impacted by SLR. Areas protected by levees in Louisiana and Texas were then masked or removed from the results. This was done for each of the emissions scenarios (Lower Emissions = 2022 Intermediate SLR Scenario Higher Emissions = 2022 Intermediate High SLR Scenario) at each of the mapped time intervals (Early Century - Year 2030, Middle Century - Year 2050, and Late Century - Year 2090). The resulting maps are displayed in the CMRA Assessment Tool. County, tract, and tribal geographies summaries of percentage SLR inundation were also calculated using Zonal Statistics tools. The Sea Level Rise Scenario year 2020 is considered “baseline” and the impacts are calculated by subtracting the baseline value from each of the near-term, mid-term and long-term timeframes.
