Only two countries - Japan and the U.S.A. - reported use of statistical projection in addition to counting. The survey did not ask how statistical projection is used. Fire statistics based on the national fire database are used for Annual Report of Fire Statistics and White Book on Fire Service annually in Japan. All other countries treat their database as a census, but it is not known whether any of these countries calculate or publish the percentage completeness of their database (for example, by calculating the percentage of total national population represented by reporting jurisdictions). In the U.S.A., the National Fire Incident Reporting System (NFIRS) is voluntary and is known to fall well short of complete capture. Accordingly, tallies based on counting are projected to “national estimates” by statistical projection, using a second database that is based on a statistically valid stratified random sample survey. An option used in the U.S.A. for a national non-fire-related incident database may be useful in other countries that do not want to shift to U.S.A.-style statistical projection for all statistics. The national crime database, maintained by the Federal Bureau of Investigation (FBI), is translated into statistics almost entirely by counting alone. However, for each major crime, there is also a calculation of the crime rate relative to population, based on the combined population of reporting jurisdictions, and the percentage of national population reporting is also reported.
