Economic activity in the United States expanded at a “modest to moderate” pace in the early part of the year, as retail sales and manufacturing grew in all but a few regions of the country, according to a survey of the Federal Reserve’s 12 districts released on Wednesday.

In the central bank survey of economic activity, compiled in what is called the beige book, severe winter weather affected some aspects of the pace of economic activity.

The report also said that labor markets improved modestly across the country, although there were differences in the types of jobs. Some regions noted stronger growth in temporary jobs while others saw an expansion in permanent positions.

“Reports from the 12 Federal Reserve Districts indicated that overall economic activity continued to expand at a modest to moderate pace in January and early February,” the beige book said. It later added: “Labor market conditions continued to strengthen modestly, with all districts reporting some degree of improvement.”
