WASHINGTON – U.S. holiday retail sales this year grew at the weakest pace since 2008, when the nation was in a deep recession. In 2012, the shopping season was disrupted by bad weather and consumers’ rising uncertainty about the economy.

A report that tracks spending on popular holiday goods, the MasterCard Advisors SpendingPulse, said Tuesday that sales in the two months before Christmas increased 0.7 percent compared with last year. Many analysts had expected holiday sales to grow 3 to 4 percent.

In 2008, sales declined by between 2 percent and 4 percent as the financial crisis that crested that fall dragged the economy into recession. Last year, by contrast, retail sales in November and December rose between 4 percent and 5 percent, according to ShopperTrak, a separate market research firm. A 4 percent increase is considered a healthy season.
