American Community Survey 2017
  -- 5-Year Public Use Microdata Sample (PUMS) data & analytics

.. the ACS 2017 PUMS 5-year microdata are available for use on January 17, 2019. There are several important uses for Public Use Microdata Sample (PUMS) files. Perhaps the most important feature is that PUMS files enable development of summary statistics for custom-defined subject matter, or crosstabs. Only a relatively small number of preplanned summary statistics are tabulated from statistical surveys such as ACS 2017. For ACS 2017, the files contain the full range of population and housing unit responses collected on the questionnaire for a subsample of ACS respondents. See list of items below.

Patterns of Economic Prosperity by Census Tract .. in context of PUMAs
PUMAs -- Public Use Microdata Areas -- are 2,378 geographic areas covering the U.S. wall-to-wall that are the primary geography for which PUMS estimates may be produced. PUMAs, shown with black boundaries in the following view, must have at least 100,000 population as of Census 2010. This view illustrates census tract geodemographics/patterns of economic prosperity (median household income) shown in context of PUMAs in the Los Angeles area. PUMAa are labeled with percent population ages 25 and over who are high school graduates.

A second important use of PUMS data is the ability to examine characteristics of individual persons or households that are identified as meeting some feature, like employed persons, or households having an income range different from those available from preplanned summary statistics. Micro-modeling is the study of patterns among some group of geographically or demographically specified group. PUMS data enable microdata analysis not possible with summary statistic data. To preserve confidentiality, PUMS data do not contain personal identifiers such as name or address.

ACS PUMS Geography .. goto top
The low level geography for which PUMS estimates can be developed are the Public Use Microdata Areas (PUMA). PUMAs, generally comprised of a set of continuous census tracts, have a population of 100,000 or more. The 2,378 PUMAs cover the U.S. wall-to-wall and are static geographic areas through the 2010s. Larger population counties are often comprised of many PUMAs. Los Angeles county has 69 PUMAs.

ACS PUMS Data Files .. goto top
ACS PUMS files are organized as person files and household files. Each record in the PUMS person file corresponds to an individual person (respondent). Each record in the PUMS household file corresponds to a single housing unit/household (for respondent). In the person-level file, individuals are organized into households, making possible the study of people within the contexts of their families and other household members. 1-year PUMS files, such as 2017, contain data on approximately one percent of the U.S. population. 5-year PUMS files, covering a five-year period, such as 2013-2017, contain data on approximately five percent of the U.S. population.

Create Your Own ACS PUMS Custom Demographic Estimates .. goto top
Use the CV XE Crosstabs tool to develop custom demographic estimates using the PUMS data for PUMAs, states and the U.S. Save the custom estimates data to file and optionally integrate those data into a PUMA or state shapefile for mapping and pattern analysis using the CV XE GIS software.

Additional Information
ProximityOne develops geodemographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses. Wide-ranging organizations use our tools (software, data, methodologies) to analyze their own data integrated with other data.
