Retailers are announcing March U.S. same-store sales figures Thursday. Research firm Retail Metrics projected an overall gain of 1.1% year-over-year. In March of 2014, retail same-store sales rose 5%. If the researchers are right, that would be the smallest increase since November 2012.

Along with its forecast, Retail Metrics noted that a softer U.S. economy with slowing job growth and a decline in hours worked could be the cause of the softness in retail sales growth. Consumers are saving more, and harsh winter weather in the North and East also had a negative impact on consumer spending.

The number of retailers reporting same-store sales has declined significantly over the past few years, but the reported numbers do provide a kind of interim report on quarterly performance at the country’s retail stores. Here is a rundown on stores that have reported sales for March:

Stein Mart Inc. (NASDAQ: SMRT) reported an 11.2% increase in same-store sales for March, a huge jump over the 2.3% growth estimate from Retail Metrics. Total sales for the month came in at $155.8 million, up 14.2% from a year ago. The company noted that March sales were “partly impacted” by the earlier Easter holiday this year.

Stein Mart’s shares were inactive in Thursday’s premarket after closing Wednesday at $12.25. The stock’s 52-week range is $11.25 to $16.65.
