The state, however, still lags behind 48 other states, with only Mississippi and Alaska returning a lower percentage of its forms, which ask 10 simple questions about each residents' age, ethnicity and gender. Puerto Rico, a U.S. territory, also has a lower rate.
As some people have noted, the official Census Day won't be here until Wednesday, and perhaps people are waiting until then to mail the forms. If that's true, it's a pattern that isn't as apparent elsewhere in the country. Texas still remains seven percentage points behind the national average of 46 percent.
