The Bureau of Labor Statistics (BLS) is a unit of the United States Department of Labor. The BLS produces Economy at a Glance pages at the national, regional, state, and metropolitan area levels. The data displayed in these pages are assembled from different surveys and programs conducted by BLS. The Economy at a Glance pages are refreshed with current data every time any of the source programs releases new statistics. This typically occurs 7-9 times per month. (Source: www.bls.gov)
