Despite all of the efforts carried out by the Census Bureau to record the number of undocumented immigrants and capture the profile of the United States' Hispanic community, its director, Robert Groves, still isn't certain that it can be achieved.

"It's an issue that still concerns us greatly, and that we are following closely. The border area between Texas and Mexico continues being problematic. It's a challenge. We still don't have sufficient information with respect to Arizona, in relation to whether the people behaved differently, but we will have it soon," he responded, when consulted by La Opinión.

The executive director of the National Association of Latino Elected and Appointed Officials (NALEO), Arturo Vargas, understood the concern in Groves' words, owing to the fact that from the beginning, 2010 emerged as a complex year. "We knew that this census was going to be the most difficult. In addition to the populations that traditionally have been difficult to count, this year also added the consequences of the economic crisis, foreclosures, and lack of employment, which have affected the Hispanic population more than any other," he explained.

Specifically, the count in areas such as Arizona – which has been the focus of controversy for the last several months – has been one of the obstacles with which the government has had to battle. Especially considering that the Hispanic population started to mobilize, or simply that they made greater efforts to pass unnoticed. The government has visited 134 million homes and is leading the final stage of this megaproject, focusing on eliminating any mistakes that may have been made. They will return to around 7.5 million homes where there is doubt regarding the number of people living there, as well as to the close to 8 million homes that were reported as vacant.

On December 31 the Census Bureau will present an official report to the President and it will be known how the count will affect the 435 seats in the House.
