  * = Value is less than half of the smallest unit of measure (e.g., for values with no decimals, the smallest unit is "1" then values under 0.5 are shown as "*".)
  Notes: See Glossary for definitions. Relative Standard Error is designed to indicate error due to sampling.  However, nonsampling error is important for all surveys, census or sample.  See Technical Notes for further information. Values for 2008 are preliminary.
