In its biannual population forecast, the bureau predicted Hawaii's population will increase by 625,000 by the year 2025. The 53 percent increase would be exceeded only by California (56 percent) and New Mexico (55 percent).

Hawaii's population in 1990, the most recent census, was 1,108,229.

Hawaii's growth rate, according to the report, will be fueled by a high birth rate and falling death rate, a slowdown in the number of people leaving Hawaii for other states and, perhaps most significantly, an influx of foreigners that is expected to be one of biggest in the nation.

"Hawaii will see a lot of immigrants and have a much younger population," said Paul Campbell, the Census Bureau demographer who wrote the report. States with high growth rates, said Campbell, "will need to plan for adjustments in facilities and services - including schools and roads - to accommodate the increased population."

The report is based on national and state demographic trends. For Hawaii, the report predicted:

By the year 2000, the state will gain 71,000 new residents.

By the year 2025, some 209,000 foreigners will immigrate to Hawaii, the 17th largest total in the nation.

Hawaii is one of only four states whose youth population will increase as a proportion of the total population over the next 30 years. The percentage of youths in Hawaii will increase from 28.8 percent in 1995 to 29.3 percent in 2025.

The state's elderly population will increase as well, from 12.6 percent of the population now to 15.9 percent in 2025. Every state in the nation, the report predicted, will experience an increase in the elderly population.

Over the next 30 years, the proportion of whites and African Americans in Hawaii will fall, while the proportion of Hispanic and Asians and Pacific Islanders will climb.
