...little higher than 20%, it was 22% back in 1960. When Johnson left office in 1969 the poverty rate had fallen to 13%.

When President Johnson came to office 22 percent of the nation's families lived in poverty (down from 30 percent in 1950). The nation's largest programs to assist the poor--Aid to Families with Dependent Children, Social Security, and Food Stamps--provided meager benefits to only a small proportion of the country's impoverished population. AFDC paid just $388 a month (in 1980 dollars) to a family of four; Social Security payments averaged just $184 a month (in 1980 dollars); and food stamps reached just two percent of the nation's poor. Medicare and medicaid did not exist. Thirty-three million poor people competed for just 600,000 public housing units.
When Johnson left office, the official poverty rate had fallen from 22 percent in 1960 to 13 percent - which is where the poverty rate remains today. AFDC payments had risen to $577 (in 1980 dollars). Infant mortality among the poor, which had barely declined between 1950 and 1965, fell by one-third in the decade after 1965 as a result of the expansion of federal medical and nutritional programs. Before the implementation of Medicaid and Medicare, 20 percent of the poor had never been examined by a physician; when Johnson retired as president the figure had been cut to 8 percent. The proportion of families living in substandard housing--that is, housing lacking indoor plumbing - also declined steeply, from 20 percent in 1960 to 11 percent a decade later.
