The Social Security Administration has announced the annual cost-of-living-adjustments for 2007. Beginning on December 29, 2006, the checks of Supplemental Security Income recipients will increase 3.3 percent, to $623 monthly. Social Security Disability Insurance recipients will see the 3.3 percent increase in their checks effective in January of 2007. This annual increase in benefits is generated automatically each year based on the rise in the Consumer Price Index.
