HAWAII NOW INCLUDED

IN REGISTRATION AREA The recent inclusion of Hawaii has extended beyond the limits of the continental United States the area for which the census bureau annually collects and publishes death statistics. Within this area now reside about 73 percent of the total population of the continental United States and Hawaii. It comprises, in all, twenty-seven states, forty-three cities in other states, the District of Columbia and the territory of Hawaii. East of the Mississippi the only states not included are Alabama, Delaware, Florida, Georgia, Illinois, Mississippi, and West Virginia, while

west of the Mississippi the only states included are California, Colorado, Kansas, Minnesota, Missouri, Montana, Utah and Washington.

The annual collection of death statistics from states and cities maintaining adequate registration systems was begun by the Census Bureau in 1902, the first report covering the calendar years 1900 to 1904, inclusive, and for each succeeding year a separate report has been published. The original registration area contained 40 percent of the total population of the country. It remained unchanged until 1906, since which year it has shown an almost uninterrupted increase.
