With a higher than expected mail return rate of 72%, no natural disasters, no flu epidemic or operational issues- The Census Bureau saved 1.6 Billion dollars. The 2010 census nearly complete, the Bureau is till conducting checks on the accuracy of its final data. The final numbers will impact the distribution of House seats as well as 400 billion in Federal aid. There had been concerns that immigrants worried over law enforcement would not participate but it is believed an effective ad campaign helped participation in the head count.
States such as New York, California, Texas, Arizona and Florida had average or below average mail-in participation rates, putting them in danger of either losing or gaining fewer than expected congressional seats
Results will be released beginning in late December. For future census surveys, the bureau will explore the use of Internet questionnaires.
