Based on per capita income, one of the more reliable measures of affluence, Eastgate ranked 38th of 522 areas in the state of Washington.

According to the United States Census Bureau, the CDP has a total area of 1.3 square miles (3.3 km2), all of it land.

[citation needed] Eastgate has tried to get annexed by Bellevue several times in the past.

In 1990, the area citizens voted to annex to the city of Bellevue and won by a majority.

On the same ballot there was an additional vote for Eastgate accepting a portion of Bellevue's bonded indebtedness.

[19] Then in 2002, the state Supreme Court decision threw out the main method cities have used for decades to expand.

[20] In addition, budget implications further postponed annexation of Eastgate with hopes of trying again in a year or two.

[22] Discussions with Bellevue have been aided by the county's agreement to give the city Coal Creek Park and the Surrey Downs district court property.

[23][24] Later in November of the same year, a budget was proposed to develop urban design and development alternatives for the Eastgate area and to conduct the first major update of the Eastgate Subarea Plan in 14 years.

The Mayor of Bellevue suggested working toward annexation of the remaining unincorporated portion of the Eastgate area and making an effort to update the subarea plan.
