The U.S. Census Bureau released population estimates at the county level. The release contains population data from 2010 to 2012.

The data include total county population and the components of population changes, but no details by age, sex, and race are available at this time.

DBEDT has reviewed the Hawaii data and produced the attached documents at the end of this email message. The web link is http://hawaii.gov/dbedt/info/economic/census/population-estimate.

Following are some interesting facts about Hawaii population from 2010 onward:

1. Between July 1, 2010 and July 1, 2012, statewide population grew at a 1.0 percent annual rate. All counties except Kauai also grew at a 1.0 percent annual rate. Kauai had an annual growth rate of 0.9 percent between 2010 and 2012.
2. The growth of the resident population between July 1, 2010 and July 1, 2012 was mainly due to natural increase (birth less death) and international migration.
3. The average number of births in the state was 18,581 a year and the average number of deaths was 10,076 per year, yielding an average natural increase of 8,505 persons between 2010 and 2012. There was an average of 7,753 net in-migrants a year from foreign countries. With a net loss of 1,947 people a year to the U.S. mainland, the result is a net gain of 5,806 people a year for the state from migration during the same time period.
4. Honolulu County accounted for 71.6 percent of the total births in the state between April 1, 2010 and July 1, 2012. Hawaii County had 12.9 percent, Maui County had 10.8 percent and and Kauai County had 4.6 percent of the state total births during the same time period. Honolulu County had 71.0 percent of the total deaths in the state, Hawaii County had 14.0 percent, Maui County had 10.0 percent,and Kauai County had 5.0 percen of the state’s total deaths between April 1, 2010 and July 1, 2012.
5. Honolulu County had more net domestic outmigration. 3,471 people moved from Oahu to the mainland from July 1, 2011 to June 30, 2012, compared to 1,076 people from July 1, 2010 to June 30, 2011.
6. Oahu had a net out migration of 2,274 people a year to the mainland, but had a net of 6,250 more people moving in from foreign countries, leaving a net gain of 3,976 people a year during the 2010-2012 period.
7. Population share among the counties in 2012 has remained the same since 2010. Honolulu County accounted for 70.1 percent of the state total resident population in 2012, followed by Hawaii County at 13.6 percent. Maui County had 11.4 percent and Kauai County had 4.9 percent of the State total population in 2012. Compared with 10 years ago, all the neighbor island counties gained population shares, while Honolulu County reduced population share due to slower growth as compared with the neighbor islands.
