RegData is the first database to count the actual number of restrictions in the Code of Federal Regulations, as opposed to the former method of simply counting total pages. The interactive tool enables a far more focused view of the regulatory burden by measuring the growth of regulation by industry. While previous methods provided an idea of the growth of overall regulation, they told nothing about how those regulations affected specific sectors in the economy. 3-digit industry codes related to health care include 621-Ambulatory Health Services; 622-Hospitals; and 623-Nursing and Residential Care Facilities. From 1997 to 2010, federal regulations increased by 170.5% in ambulatory health services, 53.8% in hospitals and 36.2% in nursing homes according to this index.
