Apparently the U.S. Census Bureau miscounted. In August, the agency reported roughly 17,000 same sex couples living in Maryland. Now, according to an article in The Sun, they’ve revised the number to 12,500.

The bureau claims that the discrepancy is due to human error in recording information onto the forms, particularly in the “name” and “sex” fields.

But even the lower, revised statistic shows a 78 percent increase in gay couples living Maryland since the 2000 census. According to demographer Gary Gates, much of that statistical increase can be credited to gay couples being more willing to disclose their sexuality in 2010 than they were ten years prior.
