What is the PAI?

Each year, the United States Department of Agriculture (USDA) produces an annual state-level PAI. The PAI provided on this page is a county-level analysis modeled on the USDA methodology.

The PAI estimates CalFresh utilization among individuals who meet select CalFresh eligibility criteria. More specifically, the PAI compares two populations: (1) CalFresh participants and (2) the number of individuals with incomes below 125 percent of the federal poverty threshold1 who do not participate in the Food Distribution Program on Indian Reservations (FDPIR)2 or receive Supplemental Security Income (SSI)3. Because the PAI incorporates three select eligibility criteria, it is not a measure of CalFresh participation among fully eligible individuals.

PAI Equation

Interpreting the PAI

The county-level PAI is one indicator of how well counties reach individuals with CalFresh. On its own, the PAI is not a comprehensive tool for evaluating counties' administration of CalFresh. Advocates and administrators should work to establish the use of additional indicators in assessing CalFresh administrative performance.

The county-level PAI is not designed to definitively establish trends over time. There are two primary challenges with using the PAI in this manner:

  1. Methodological approaches may change over time, altering the comparability of PAI estimates calculated before and after each change.
  2. Income data from the American Community Survey are used to calculate the PAI. These data have a given level of precision expressed as a margin of error. Margins of error can make it difficult to distinguish true trends from variations inherent to the methods used for collecting and analyzing survey data.

Comparing the PAI and State Participation Rates

Each year, USDA releases SNAP/CalFresh participation rates for all 50 states and the District of Columbia. These participation rates are complex estimates of SNAP/CalFresh utilization among eligible individuals. The rates take into account several factors affecting SNAP/CalFresh eligibility and utilization. In comparison, the PAI takes into account three CalFresh eligibility criteria: income, FDPIR participation, and SSI status.

State participation rates for any given year are typically released two years following. In comparison, the PAI can be calculated within one year.

USDA state participation rates may be the best available estimates of CalFresh utilization among eligible individuals. However, the rates are calculated as statewide measures and have limited relevance at the county level, particularly in a state as diverse as California. USDA does not calculate county-level participation rates. Because CalFresh policies and practices vary across California counties, county-level indicators of utilization and administrative performance are necessary. The PAI is one such indicator.

PAI Tables

The tables below show the PAI for all 58 California counties and include county rankings. The number-one-ranked county has the highest CalFresh utilization relative to the total number individuals with incomes below 125 percent of poverty who do not participate in FDPIR or receive SSI.4

Table 1 lists the counties alphabetically. Table 2 lists the counties by PAI rank.

Table notes 1-2: The PAI is listed here with three significant digits. However, the PAI used to calculate the county ranking contained 15 significant digits. Viewed with four significant digits, Amador County’s PAI is 0.7829 and Shasta County's PAI is 0.7827. Thus, their respective ranks are 16 and 17. Similarly, Riverside County’s PAI is 0.6814 and Tehama County’s PAI is 0.6812.

_______________________

1 Eligibility criteria for CalFresh allow participants to have incomes up to 130 percent of the federal poverty guidelines (FPG). However, annual county-level estimates are not available for the number of individuals with incomes below 130 percent of FPG. Therefore, having an income below 125 percent of the federal poverty threshold is used as a proxy for CalFresh income eligibility. The use of this proxy may underestimate the number of individuals who are income-eligible for CalFresh.

2 FDPIR participants are not eligible for CalFresh.

3 In California, SSI recipients are not eligible for CalFresh/SNAP.

4 For Tables 1 and 2, all Supplemental Security Income (SSI) participants are subtracted from the population of individuals who are income-eligible for CalFresh. An adjunct set of PAI tables, for which the estimated SSI population with income below 125 percent of poverty is subtracted from the population of individuals who are income-eligible for CalFresh, is appended in the full report.
