Identification Information

Abstract A broad and generalized selection of 2012-2016 US Census Bureau 2016 5-year American Community Survey poverty data estimates, obtained via Census API and joined to the appropriate geometry (in this case, New Mexico Census tracts). The selection is not comprehensive, but allows a first-level characterization of populations living below the poverty level, as grouped by age, sex, education, workforce status, and nativity. The determination of which estimates to include was based upon level of interest and providing a manageable dataset for users.The U.S. Census Bureau's American Community Survey (ACS) is a nationwide, continuous survey designed to provide communities with reliable and timely demographic, housing, social, and economic data every year. The ACS collects long-form-type information throughout the decade rather than only once every 10 years. The ACS combines population or housing data from multiple years to produce reliable numbers for small counties, neighborhoods, and other local areas. To provide information for communities each year, the ACS provides 1-, 3-, and 5-year estimates. ACS 5-year estimates (multiyear estimates) are “period” estimates that represent data collected over a 60-month period of time (as opposed to “point-in-time” estimates, such as the decennial census, that approximate the characteristics of an area on a specific date). ACS data are released in the year immediately following the year in which they are collected. ACS estimates based on data collected from 2009–2014 should not be called “2009” or “2014” estimates. Multiyear estimates should be labeled to indicate clearly the full period of time. While the ACS contains margin of error (MOE) information, this dataset does not. Those individuals requiring more complete data are directed to download the more detailed datasets from the ACS American FactFinder website. This dataset is organized by Census tract boundaries in New Mexico. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2010 Census Participant Statistical Areas Program. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.
Purpose Provide general users with a selection of poverty data available from the US Census Bureau's American Community Survey (ACS) 5-year estimates from 2012-2016, within the frame of reference of the US Census TIGER/Line Census Tracts for New Mexico.
Supplemental Information This work was influenced by the work of Todd Bleess at the Colorado State Demography Office, especially his renaming of the source (ACS) attributes into more human-readable names.

Currentness Reference Temporal extent is twofold: 1. the underlying data derives from the 2012-2016 ACS 5-year estimates, as well as the time period during which the tract boundaries are considered still valid. 2. the dataset itself is valid as a means of comparison for similar data from other time periods (such as different 5-year ACS publications). As ACS 5-year datasets are not released until subsequent years (2013-2017 was released in December of 2018, 2014-2018 should be released in December of 2019, and so on).

Use Constraints No limitations from RGIS. The source geometry for this dataset is a TIGER/Line shapefile.

These products are free to use in a product or publication, however acknowledgement must be given to the U.S. Census Bureau as the source. The boundary information in the TIGER/Line Shapefiles are for statistical data collection and tabulation purposes only; their depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership or entitlement and they are not legal land descriptions.Coordinates in the TIGER/Line shapefiles have six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest.

Process Description Obtain a select group of Bureau of Census data from latest availalble ACS 5-year estimate using Census API. Census API calls are limited to 50 fields/attributes per call, and are typically run as an URL, using a browser, the curl command line too, or from within a script. The data from the Census API is serialized into a dataframe.
