The city is weathering a national retail downturn.

Brick-and-mortar retail stores employed 343,400 workers in the city in March, up 0.4 percent from the previous month and rising 8 percent since March 2012, state labor records show.

The country added about 6,300 retail jobs in April but that did little to make up the 29,700 retail jobs shed in March and 31,000 jobs lost in February, federal labor records say.

Most of the city’s gains were in grocery shops.
