Census Data to Target the Uninsured

View and export 2 tables of data identifying geographic locations of eligible uninsured populations:

You can filter or sort this data on several population characteristics, including federal poverty level, education, and language. Descriptions of all data fields are below. You can also export this data to the format you choose (Excel, etc.) and use the FIPS codes to produce maps. Detailed maps of the PUMAs in each state are available from the Census Bureau.

The data here are for outreach targeting purposes only. They are not suitable for program evaluation or estimating program impact. The number of people with incomes at varying federal poverty levels is based on data from the Census for 2011 and may vary from 2014 estimates. They are good estimates to direct outreach efforts, but are not direct measures of the number of people who may be eligible for coverage through the Marketplace and Insurance Affordability Programs, including Advance Payments of the Premium Tax Credit/Cost Sharing Reductions, Medicaid, CHIP and the Basic Health Program, if applicable.

Data to estimate eligible uninsured

The Census Bureau’s American Community Survey (ACS) and imputations described below were used to develop these estimations. ACS is a publicly available survey that lists the geographical home for each household at the level of the "Public-Use Microdata Area," also called PUMAs, for households in all 50 states and the District of Columbia.  

Each PUMA is an area within a single state that contains at least 100,000 residents. In sparsely populated areas, PUMAs typically comprise one or more neighboring counties within a given state. In densely populated areas, PUMAs may be limited to smaller areas within a county, such as several Census tracts in a given city. 2011 ACS data were used for these analyses.

ASPE tabulations from CY 2011 American Community Survey Public Use Microdata Sample (ACS PUMS), adjusted to exclude estimated undocumented persons.  The adjustment methodology is based on imputations of immigrant legal status in ASPE's TRIM3 microsimulation model (http://trim.urban.org/), according to methods initially developed by Jeffrey Passel and Rebecca Clark.  The imputations of immigrant legal status developed by Jeffrey Passel for the Spring 2009, 2010, and 2011 Current Population Survey Annual Social and Economic Supplement (CPS-ASEC) data on CY 2008-2010 were used to estimate the probability that a noncitizen in the ACS PUMS data was a legal resident of the United States.  These probabilities—varying by reported status as insured or uninsured, state, race/ethnicity, income, and age—were then used to reweight the ACS PUMS data and produce the adjusted tabulations.  A technical description of the imputation will be available.

Methods

  • The Office of the Assistant Secretary for Planning and Evaluation estimated the number of eligible uninsured people living in each PUMA in the U.S., with additional details on the numbers and percentages of eligible uninsured people based on several variables. See below for full variable list and definitions.  
  • The data includes 2  versions: one shows the percentage of the eligible uninsured population that falls within each category (e.g. percentage of all eligible uninsured individuals who are under 18); the other shows the absolute number of eligible uninsured individuals within each category. 
  • All estimates are survey-weighted and represent the total eligible uninsured population ages 0-64.
  • Any data cell containing a weighted average of less than or equal to 0.5% was rounded to 0% (except in national data totals).

Variables

  • ID: Sequentially numbered 1 through 2069 for all the PUMAs in the 50 states + D.C.
  • State Name: State name or District of Columbia, for each PUMA.
  • State FIPS: State numeric code, from the Federal Information Processing Standards.
  • PumaState: Unique PUMA identifier, which combines state and PUMA information, using the formula StateFIPS*100000 + Puma ID
  • PUMA: Puma ID number, which identifies a PUMA within its own state (but the same PUMA number can be used by different states).
  • Counties within PUMA: List of counties partially or fully contained within each PUMA.
  • CountyFIPS: County numeric code for PUMAs containing only one county.  CountyFIPS is not reported for PUMAs containing more than one county.
  • Uninsured Total: Total number of individuals, ages 0-64, in each PUMA without any health insurance.
  • Uninsured Percent: Percentage of individuals, ages 0-64, in each PUMA who are without any health insurance.

Remaining variables all refer to either the number or percentage of uninsured individuals who fall into the following categories:

  • Age0_18: Uninsured individuals 18 years or younger

For several variables (family income, worker in the family, child in the family), we defined "family" based on the "health insurance unit" (HIU), which includes adults, their spouses, and their dependent children (ages 0-18, plus full time students under 23), using ASPE analysis of the ACS data. Precise definitions of HIUs using survey data vary, which can produce small differences in HIU-related estimates from different analysts not using ASPE’s approach.
