It’s official — Hawaii is just a little bit older than it was a decade ago.

New data shows that the median age in the islands is now 38.6 years old, up from 36.2 in the 2000 Census.

An announcement from the Census released early Thursday morning Eastern time by the U.S. Census Bureau also shows Hawaii’s average household size was 2.89 people and among the state’s occupied housing units, 57.7 percent were owned, compared with 42.3 percent that were rented.

The first batch of 2010 Census data was revealed earlier this year and included the state’s total population, racial breakdown (for those who identified one race only), vacant and occupied housing units and number of Hispanic residents.

The new data — as of this writing available for download via FTP but not included in the American FactFinder system until 4 a.m. Hawaii time — includes far more detail: counts of males and females of all ages, race alone and in combination and relationship between householders and their co-habitants, for example.

Civil Beat will take a more detailed look at the data soon. For now, review our coverage from the earlier Census release as well as the American Community Survey results, based on a poll of a sample of the population:
