Social Security benefits for nearly 58 million people will rise only 1.5 percent next year, among the smallest increase since automatic adjustments were adopted in 1975, the government announced Wednesday.
The cost-of-living adjustment, or COLA, is based on a government measure of inflation that was released Wednesday.

The increase was small because consumer prices, as measured by the government, haven't gone up much in the past year.
The COLA affects benefits for more than one-fifth of the country, including millions of disabled veterans, federal retirees and people who get Supplemental Security Income, the disability program for the poor.
