As administrative records change, much of the source data for health statistics will change.
For example, the spread of Electronic Health Records will make it possible to compile more statistical information about conditions coming to the attention of providers and the health care they provide.
How to find the data
Health statisticians summarize data from these sources in several series. For example, vital statistics information in the United States is compiled by state health departments and reported to the National Center for Health Statistics. Analysts working at NCHS issue a number of key statistical reports which can be found at //www.cdc.gov/nchs/nvss.htm .
