A decade in the making, the 2010 U.S. Census has finally made it to Hawaii.

State government leadership on Wednesday received FedEx deliveries from the Census Bureau. Now is the time when years of projection, estimation and speculation become a reality.

With a big assist from Hawaii Senate Majority Leader Brickwood Galuteria‘s office, Civil Beat is proud to give you the first look at official population counts and race, ethnicity and occupancy data for the state as a whole as well as Hawaii’s four counties and two Congressional districts.

The full data tables, all in PDF form:

A quick look at the data shows that the annual population estimates for the four counties were moving in the right general direction, but were far from perfect. Even the most recent estimate — July 1, 2009 was only nine months before the official “Census Day” of April 1, 2010 — was more than 45,000 off on the Oahu population.

It did, however, hit the counties’ respective proportions on the head. Island-by-island population shares — which we explored previously as we tried to figure out if the Big Island would gain a Hawaii House district this year — remained steady:

We hope you’ll check out Civil Beat’s earlier coverage of Hawaii’s shifting demographics, produced from the American Community Survey results. While that survey has replaced the long-form Census of yesteryear, today is still a big day.

Full data will be widely available Thursday after the Census Bureau updates its maps and American FactFinder tool. We’ll share what we find as soon as we find it.
