Zip code boundaries from Los Angeles County.

The geometry of this shapefile was derived from the parcel specific ZIP Code Boundaries used by Los Angeles County's geocoding services, also available on the Los Angeles County GIS Data Portal. The 19 regional offices of the Department of Children and Family Services (DCFS) use these boundaries to provide services and resources to the children and families of the different geographic areas within Los Angeles County.DCFSOFFICE: DCFS Regional Office assigned to this ZIP CodeD_SPA: Dominant Service Planning Area (SPA)OFFC_CODE: Internal DCFS useD_ADDR1: Address Line 1D_ADDR2: Address Line 2D_PHONE: PhoneGMAP_URL: Google Maps URL for directionsOFFC_X: CCS83 Zone 5 XOFFC_Y: CCS83 Zone 5 YDCFSLBL: Regional Office LabelZIPTXT: ZIP Code text valueZIP: ZIP Code numeric valueCOMMUNITY: Postal CityC_TYPE: Community TypeZIPTYP: ZIP Code TypeCOLOR_EGIS: Assigned color used in mappingCOLOR_HEX: Same assigned colors, expressed as hex valuesFor more information, visit the home site at https://dcfs.lacounty.gov/contact/regional-offices/Child Abuse Hotline, accessible 24 hours per day, 7 days a week: (800) 540-4000 or visit https://dcfs.lacounty.gov/contact/report-child-abuse/

This polygon shapefile represents zip code tabulation areas (ZCTAs) for the state of California. These data were gathered from the 2010 Census demographics update and contain keys for ZCTAs, centroid coordinates, demographic fields for age, gender, race and ethnicity, and housing information including living quarters, institutionalized populations, households and housing units. For the 2010 Census, there were no “XX” or “HH” ZCTAs assigned. Only five-digit ZCTAs were produced, and large unpopulated areas were excluded from the delineations. For the 2010 Census, there is no wall-to-wall national coverage for ZCTAs. Large water bodies and unpopulated land area such as national parks were excluded from the 2010 delineations, and for this reason the Census 2010 product does not have complete national coverage.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery. The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros. Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists. The ZCTA boundaries in this release are those delineated following the 2010 Census.

Blocks are typically bounded by streets, roads or creeks. In cities, a census block may correspond to a city block, but in rural areas where there are fewer roads, blocks may be limited by other features. The Census Bureau established blocks covering the entire nation for the first time in 1990.There are less number of Census Blocks within Los Angeles County in 2020 Census TIGER/Line Shapefiles, compared in 2010.Updated:1. June 2023: This update includes 2022 November Santa Clarita City annexation and the addition of "Kinneloa Mesa" community (was a part of unincorporated East Pasadena).

Context

In order to complete our group project, which is abour developing a website to find vaccine station in Los Angeles County, in EE599 USC. We scraped two website to get our dataset.

Content

At first, we scraped the Los Angeles Almanac to get the whole zip codes of Los Angeles County. The zip codes are store in zipcode.json. It will include some zip codes, which are not used nowadays.

Los Angeles County: http://www.laalmanac.com/communications/cm02_communities.php

Secondly, we scraped Google Map to get the position of each zip code. The position is presented by the form of latitude and longitude. The postion info is stored in zip2pst.json.

At last, we scraped the VaccineFinder to get the information about the providers info and vaccine information, which are stored in porviders.json and providers_info.json. VaccineFinder: https://www.vaccines.gov/

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

The Justice Equity Services Index (JESI), by Advancement Project California, provides policymakers and advocates with the ability to detect where there are greater or fewer community-based organizations providing the vital services needed to support the communities most impacted by our justice system.The JESI groups service types into four main components to align with the broader service spectrum embraced by initiatives such as Measure J and the ATI Initiative, they include: Health & Wellness, including behavioral and physical health and wellbeing services. Housing & Employment, including housing, shelter, employment, and career training services. Prevention & Intervention, including prevention, reentry, and youth development services. Community Services & Advocacy, including human services, advocacy, and community action services. The JESI offers advocates a comprehensive picture of community-based, justice-related, care-first providers and their functions in L.A. County. Each JESI component also includes a unique score to give a more nuanced view of where there is greater or lesser service capacity for each essential justice-related service.

"Field Name = Field Definition "Zipcode" = postal zip code in the City of Los Angeles “Percent” = estimated percentage of adult respondents ages 18+ who were ever diagnosed with asthma by a doctor"LowerCL" = the lower 95% confidence limit represents the lower margin of error that occurs with statistical sampling"UpperCL" = the upper 95% confidence limit represents the upper margin of error that occurs in statistical sampling "Population" = estimated population 18 and older (denominator) residing in the zip code Notes: 1) Zip codes are based on the Los Angeles Housing Department Zip Codes Within the City of Los Angeles map (https://media.metro.net/about_us/pla/images/lazipcodes.pdf).2) Zip codes that did not have data available (i.e., null values) are not included in the dataset; there are additional zip codes that fall within the City of Los Angeles.3) Zip code boundaries do not align with political boundaries. These data are best viewed with a City of Los Angeles political boundary file (i.e., City of Los Angeles jurisdiction boundary, City Council boundary, etc.) FAQS: 1. Which cycle of CHIS does AskCHIS Neighborhood Edition provide estimates for?All health estimates in this version of AskCHIS Neighborhood Edition are based on data from the 2013-2014 California Health Interview Survey. 2. Why do your population estimates differ from other sources like ACS? The population estimates in AskCHIS NE represent the CHIS 2013-2014 population sample, which excludes Californians living in group quarters (such as prisons, nursing homes, and dormitories). 3. Why isn't there data available for all ZIP codes in Los Angeles?While AskCHIS NE has data on all ZCTAs (Zip Code Tabulation Areas), two factors may influence our ability to display the estimates:A small population (under 15,000): currently, the application only shows estimates for geographic entities with populations above 15,000. If your ZCTA has a population below this threshold, the easiest way to obtain data is to combine it with a neighboring ZCTA and obtain a pooled estimate.A high coefficient of variation: high coefficients of variation denote statistical instability.
