About United States Richmond Fed Services Index
The data come from the Fifth District Survey of Service Sector Activity. Respondents to the survey are firms located within the Fifth Federal Reserve District which includes the District of Columbia, Maryland, North Carolina, South Carolina, Virginia, and most of West Virginia. Respondents indicate whether measures of activity rose, were unchanged, or decreased since the last survey. The responses are converted into diffusion indexes by subtracting the percentage of reported decreases from the percentage of increases.
