NOTE: Percentages are rounded to the nearest tenth of a percent; therefore, the percentages in a distribution do not always add to exactly 100 percent. The totals, however, are always shown as 100. Moreover, individual figures are rounded to the nearest thousand without being adjusted to group totals, which are independently rounded; percentages are based on the unrounded numbers.
Source of Data
The estimates in this report come from data obtained in March 1999 from
the Current Population Survey (CPS). The Census Bureau conducts the CPS
every month, although this report uses only data from the March survey.
Accuracy of the Estimates
Statistics from surveys are subject to sampling and nonsampling error.
All comparisons presented in this report have taken sampling errors into
account and meet Census Bureau standards for statistical significance.
Nonsampling errors in surveys may be attributed to a variety of sources,
such as how the survey was designed, how respondents interpret questions,
how able and willing respondents are to provide correct answers, and how
accurately the answers are coded and classified. The Census Bureau
employs quality control procedures throughout the production process -
including the overall design of surveys, the wording of questions, review
of the work of interviewers and coders, and statistical review of reports.
The Current Population Survey employs ratio estimation, whereby sample
estimates are adjusted to independent estimates of the national population
by age, race, sex, and Hispanic origin. This weighting partially corrects
for bias due to undercoverage, but how it affects different variables in
the survey is not precisely known. Moreover, biases may also be present
when people who are missed in the survey differ from those interviewed in
ways other than the categories used in weighting (age, race, sex, and
Hispanic origin). All of these considerations affect comparisons across
different surveys or data sources.
