HOW IS THE CONSISTENCY OF THE DATA MAINTAINED?
BNIA-JFI has gone to great lengths to maintain consistency in the sources and time series of the indicators and data collected; however over time some of the indicators tracked by BNIA-JFI have changed. These changes are the result of several reasons including: data no longer being collected or maintained by data providers; a change in the geographic level of the data being collected; cost of the data purchased by BNIA-JFI; or availability of new data sources. Changes in data for Vital Signs 8 are listed in Vital Signs 8 Changes and Explanations.
