Researchers David Autor and Mark Duggan have hypothesized that the Social Security benefit formula using the average wage index, coupled with a widening distribution of income, has created an implicit rise in replacement rates for low-earner disability beneficiaries. This research attempts to confirm and quantify the replacement rate creep identified by Autor and Duggan using actual earnings histories of disability-insured workers over the period 1979–2004. The research finds that disability replacement rates are rising for many insured workers, although the effect may be somewhat smaller than that suggested by Autor and Duggan.

This article examines pension participation and nonpension net worth of two cohorts of near retirees. Particularly, the authors look at people born in 1933 through 1939 who were ages 55–61 in 1994, and the more recent cohort consisting of people of the same age in 2004 who were born in 1943 through 1949. Data are from the Health and Retirement Study, a longitudinal, nationally representative survey of older Americans.

With the death of Robert Myers Ball at age 93 on January 29, 2008, the Social Security program lost one of its most committed supporters. In 2001, Ball's biographer, historian Edward D. Berkowitz, described Ball as "the major non-Congressional player in the history of Social Security in the period between 1950 and the present."

In a federal government career that lasted more than four decades, Mollie Orshansky worked for the Children's Bureau, the Department of Agriculture, the Social Security Administration, and other agencies. While working at the Social Security Administration during the 1960s, she developed the poverty thresholds that became the federal government's official statistical measure of poverty; her thresholds remain a major feature of the architecture of American social policy and are widely known internationally.
