U.S. Census Bureau American Community Survey (1 Year Estimates); Table B05003 SEX BY AGE BY NATIVITY AND CITIZENSHIP STATUS
In order to get estimates for places in Arizona with smaller populations we have used the American Community Survey 3 and 5 year estimates, when available.
The American Community Survey is based on sample sizes and the numbers presented in this indicator are just estimates and are not to be taken as accurate counts.
S - Estimates suppressed when the confidence interval around the percentage is greater than or equal to 10 percentage points.
N/A - Data not available
The Census Bureau recommends that you:
DO compare similar period lengths, for example, 3-year to 3-year.
DON'T compare estimates from different period lengths, for example, 1-year to 3-year.
DO compare estimates from non-overlapping periods, for example, compare a 2005-2007 ACS 3-year estimate to a 2008-2010 ACS 3-year estimate.
DON'T compare overlapping periods, for example, the 2005-2007 ACS 3-year estimates to the 2006-2008 ACS 3-year estimates.
