Social Security Administration (SSA) Staffing Levels: Data Brief

Social Security Administration (SSA) Staffing Levels: Data Brief

Updated April 23, 2026 (R48725)

Introduction

The Social Security Administration (SSA) is an independent agency in the executive branch headed by the commissioner of Social Security. It is responsible for administering Social Security and Supplemental Security Income, which are the nation's primary income support programs for older adults and individuals with disabilities. SSA is also responsible for supporting the administration of a number of non-SSA programs and activities, such as portions of Medicare.

This report provides selected data on SSA's recent and historical staffing levelsincluding state disability determination services (DDS) staffing levelsacross a number of different metrics. The recent and historical periods used in this report are based, in part, on the public availability of data for each metric. For data on SSA's recent and historical staffing levels by state or area, see CRS Report R48911, Social Security Administration (SSA) Staffing Levels by State or Area: Data Brief. For additional data on SSA's staffing levels, see the Office of Personnel Management's (OPM's) Federal Workforce Data website at https://data.opm.gov/.

Table 1 shows estimated SSA staff on duty from agency contingency plans, by office, for 2018-2025. Entries for some offices are blank (i.e., "—") because the office did not exist at the time or no longer exists. SSA underwent several reorganizations in 2025 that closed some offices, created new offices, and transferred staff and functions to different offices. As a result, office-level staffing data for 2025 may not be comparable with previous years.

Notes: "—" = not applicable. The staff counts are estimated for the end of September or the beginning of October of the year shown using actual staff counts from July or August of that year. The office Operations includes field offices, teleservice centers, regional offices, program service centers, and the Office of Central Operations. The Inspector General data for 2025 were calculated based on the difference between the higher staffing total at the beginning of the 2025 contingency plan and the lower total in the table at the end of the plan.

Table 2 shows full-time equivalent (FTE) employees, by component, for FY2019-FY2026. An FTE is the equivalent of one employee working full-time for one year (2,080 hours), excluding overtime and lump-sum leave. The table separates out SSA's Office of the Inspector General (OIG) from the rest of the agency. It also provides data on state DDSs, which are state agencies that conduct disability determinations and reviews on behalf of, and under agreements with, SSA. State DDS personnel are state employees, and their salaries and related activities are fully funded by SSA, subject to certain conditions. The FY2026 data in the table are estimates from SSA's FY2027 congressional budget justification.

Notes: The FY2026 data are through February 2026.

Figure 3 shows SSA total work years for FY1964-FY2026. SSA calculates total work years as the sum of FTE employment and overtime and lump-sum leave (i.e., the number of FTE employees plus the number of overtime and lump-sum leave work years). The figure displays two types of work-year metrics: LAE-only activities (FY1964-FY2026) and all activities (FY1975-FY2026). The metric LAE-only activities includes only those work years that are attributable to SSA's Limitation on Administrative Expenses (LAE) account or equivalent historical account. The LAE account is SSA's primary administrative appropriations account and funds SSA's activities related to Social Security, SSI, and portions of Medicare.1 The metric all activities includes LAE work years in addition to work years that are attributable to reimbursable work,2 SSA's OIG,3 special temporary workloads,4 and, prior to FY1998, certain other programs and activities for which SSA had administrative responsibilities.5 Figure 4 shows state DDS total work years for FY1980-FY2026. The FY2026 data in both figures are estimates from SSA's FY2027 congressional budget justification.

Appendix. Data Underlying Historical Staffing Figures and Additional Data

Table A-1 provides the data underlying the historical staffing figures shown in the body of the report. The table includes additional years of data for SSA total staff on duty (SSA data) and SSA total work years (LAE-only activities), as well as data on SSA full-time permanent staff, SSA and OIG FTEs, and state DDS total staff on duty. Data for some metrics are not available for all years shown below, because CRS was unable to find publicly available data for certain years. In some cases, the entries for certain metrics are blank (i.e., "—") because the particular metric was not captured or produced by SSA at that time or the particular entity did not exist at that time (e.g., SSA's OIG was established in the second half of FY1995).

Notes: "—" = not available or not applicable. The data for SSA Total Staff on Duty for FY1936-FY1946 are for the Social Security Board, which was replaced by SSA in July 1946. For the metric SSA Full-Time Permanent Staff on Duty, the SSA data include seasonal employees, while the OPM data exclude seasonal employees. The data for LAE-Only Activities for FY1941-FY1962 are for the Bureau of Old-Age and Survivors Insurance. Prior to FY1979, the President's budget referred to the LAE account as the Limitation on Salaries and Expenses account, the Salaries and Expenses account, or the Salaries account. The data for LAE-Only Activities and SSA FTEs exclude reimbursable work. (The SSA FTE data for FY2023-FY2026 in Table 2 include reimbursable work.) The FY1972-FY1978 and FY2025 data for State DDS Total Staff on Duty are rounded. The FY2026 data for SSA Total Staff on Duty and SSA Full-Time Permanent Staff on Duty are through February 2026. The FY2026 data for SSA Total Work Years, SSA and OIG FTEs, and State DDS Total Work Years are estimates from SSA's FY2027 congressional budget justification.
