The population and housing unit estimates are released on a flow basis throughout each year. Each new series of data (called vintages) incorporates the latest administrative record data, geographic boundaries, and methodology. Therefore, the entire time series of estimates beginning with the date of the most recent decennial census is revised annually, and estimates from different vintages of data may not be consistent across geography and characteristics detail.
When multiple vintages of data are available, the most recent vintage is the preferred data.

The vintage year (e.g., V2021) refers to the final year of the time series. The reference date for all estimates is July 1, unless otherwise specified.

Additional estimates files may also be accessed via the Census Bureau application programming interface (API).

Additional information on the Census Bureau's Population Estimates Program (PEP) is available on the PEP's homepage Census Bureau's Population Estimates Program.

Notes: For vintage 2019: The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program and geographic program revisions. All geographic boundaries for the 2019 population estimates are as of January 1, 2019.

For vintage 2021: The estimates are developed from a base that incorporates the 2020 Census, Vintage 2020 estimates, and 2020 Demographic Analysis estimates. The estimates are developed from a base that incorporates the 2020 Census, Vintage 2020 estimates, and 2020 Demographic Analysis estimates.

The PA Department of Conservation and Natural Resources (DCNR) and PA Game Commission (PGC) have teamed up to create an interactive map specifically for hunters. Collectively, State Forest Land and Gamelands comprise over 3.7 million acres of public forest open to hunting in Pennsylvania. Hunters can use this map to:View public forests open to hunting.Search hunting seasons and bag limits across different parts of the state.Display hunting hours (starting/ending times) across different parts of the state.Add personal GPS data to the map (waypoints and tracklogs).View different types of wildlife habitat across public forest lands, including mature oak forests, meadows, food plots, openings, winter thermal (coniferous) cover, and young aspen forest.See where recent timber harvests have occurred on public forest lands.Get deer management assistance program (DMAP) information for state forest lands.Add map layers associated with chronic wasting disease (CWD).Identify where bear check stations are located and get driving directions.Display the elk hunting zones and get information about them.Get the location of gated roads opened for hunters on public forest lands and when those gates will be opened.Analyze graphs and trends in antlerless/antlered deer harvests and antlerless license allocations from 2004 to the present.

This web map presents a flood hazard assessment of Luzerne County, PA.

Populations along the Susquehanna River Basin, which includes areas of New York, Pennsylvania, and Maryland, reside in one of the most flood prone areas in the United States. Major floods have occurred about every 15 years and flash floods are a consistent threat. Luzerne County, PA communities have long histories of flood emergencies, as the river bisects the county and tributaries are spread throughout. Based on the existing models and historical data, flood protection and management are already high priorities. However, rapidly changing demographics and unpredictable environmental conditions expose the need for more detailed and constantly evolving models for emergency preparedness and response.

This Hazard Analysis of Luzerne County augments the existing flood hazard area models with two additional critical factors for consideration. First, areas with vulnerable populations are identified using the Agency for Toxic Substances and Disease Registry's (ATSDR) 2014 Social Vulnerability Index. This data model incorporates a variety of socioeconomic indicators as part of an analytical matrix that measures the potential resilience of communities facing emergency conditions. All tracts are given a percentile rank (0= Lowest Vulnerability to 1=Highest Vulnerability) for fifteen variables. Four major theme rankings (Socioeconomic, Housing Composition and Disability, Minority Status & Language, and Housing & Transportation) are compiled as a sum of the variables for each theme. An overall percentile ranking is determined for each tract. For the purposes of this study, Natural Breaks classification was used to group tracts with similar overall tract scores. All tracts with overall ratings above .7372 (top 2 of 5 classes) are defined as “High Vulnerability”, with populations that are at the highest risk during crisis level events of any kind. In addition, critical infrastructure locations are identified and mapped.

Given the incalculable value of human life and importance of essential infrastructure to response and recovery, both the “High Vulnerability” areas and critical emergency locations layers are intersected with a layer of flood hazard areas from the FEMA Flood Map Service Center. The Special Flood Hazard Areas (SFHA) that intersect with High Vulnerability areas are defined as “High Hazard Areas”.

The United States National Grid (USNG) for Luzerne County is also available as a comparative layer.

About the SFHA

The land area covered by the floodwaters of the base flood is the Special Flood Hazard Area (SFHA) on NFIP maps. The SFHA is the area where the National Flood Insurance Program's (NFIP's) floodplain management regulations must be enforced and the area where the mandatory purchase of flood insurance applies.

What is the SVI?

Social vulnerability refers to the resilience of communities when confronted by external stresses on human health, stresses such as natural or human-caused disasters, or disease outbreaks. Reducing social vulnerability can decrease both human suffering and economic loss. The Agency for Toxic Substances and Disease Registry's (ATSDR) Social Vulnerability Index uses U.S. census variables at tract level to help local officials identify communities that may need support in preparing for hazards or recovering from disaster.

What is the USNG?

The United States National Grid (USNG) is a point reference system of grid references commonly used in the United States. It provides a nationally consistent language of location in a user-friendly format. It is similar in design to the national grid reference systems used throughout other nations.

This EnviroAtlas dataset describes the block group population and the percentage of the block group population that has potential views of water bodies. A potential view of water is defined as having a body of water that is greater than 300m2 within 50m of a residential _location. The residential locations are defined using the EnviroAtlas Dasymetric (2011 version) map. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas ) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

As included in this EnviroAtlas dataset, the community level domestic water use was calculated using locally available water use data per capita in gallons of water per day (GPD), distributed dasymetrically, and summarized by census block group. Domestic water use, as defined in this case, is intended to represent residential indoor and outdoor water use (e.g., cooking hygiene, landscaping, pools, etc.) for primary residences (i.e., excluding second homes and tourism rentals). For the purposes of this metric, these publicly-supplied estimates are also applied and considered representative of local self-supplied water use. Domestic water demand was calculated and applied using the Pennsylvania Department of Environmental Protection (PADEP) PWS Service Areas layer, population served per provider, and average water use per provider. Within the EnviroAtlas study area, there are 43 service providers with 2010-2013 estimates ranging from 34 to 102 GPD.

This EnviroAtlas dataset shows the total block group population and the percentage of the block group population that has little access to potential window views of trees at home. Having little potential access to window views of trees is defined as having no trees and forest land cover within 50 meters. The window views are considered "potential" because the procedure does not account for presence or directionality of windows in one's home. In this community, tree cover is defined as Trees & Forest, Orchards, and Woody Wetlands.
