Census Day is a key reference day for the once-every-decade count, according to the bureau. When completing the census, respondents are asked to include everyone living in the home on April 1. This is the first time the 10-year census has been largely taken via internet response.
In Texas, roughly 29% of the responses have been online, while the U.S. is showing nearly 34% as of March 31.
This feature has become more critical now that COVID-19 has begun affecting census door-to-door data collection for those who have not yet responded. Field operations by the U.S. Census Bureau have been suspended until at least April 15, according to the bureau.
