If you feel like your Social Security check doesn't stretch as far as it once did, there's a likely explanation for it.
Since 2000, the buying power of monthly benefits has fallen by more than a third, according to an annual report released Thursday by the Senior Citizens League, an advocacy group based in Alexandria, Virginia.
In other words, the cost of goods and services common among retirees have collectively risen faster than the cost-of-living adjustment, or COLA, that Social Security recipients get every year.
"People who recently retired might have seen only a [small] decrease in buying power," said Mary Johnson, a policy analyst for the league. "But those retired for a long time are feeling the cumulative effect of this."
