2006-2010 American Community Survey 5-Year Estimates
Supporting documentation on code lists, subject definitions, data accuracy, and statistical testing can be found on the American
Community Survey website in the Data and Documentation section.

Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on the Am
Community Survey website in the Methodology section.
Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, for 2010, the
Census provides the official counts of the population and housing units for the nation, states, counties, cities and towns. For 20
the Population Estimates Program provides intercensal estimates of the population for the nation, states, and counties.

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sam
variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The mar
can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate minus the margin of err
estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling varia
ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The eff
nonsampling error is not represented in these tables.


While the 2006-2010 American Community Survey (ACS) data generally reflect the December 2009 Office of Management and
(OMB) definitions of metropolitan and micropolitan statistical areas; in certain instances the names, codes, and boundaries of t
cities shown in ACS tables may differ from the OMB definitions due to differences in the effective dates of the geographic entitie


Estimates of urban and rural population, housing units, and characteristics reflect boundaries of urban areas defined based on
2000 data. Boundaries for urban areas have not been updated since Census 2000. As a result, data for urban and rural areas f
ACS do not necessarily reflect the results of ongoing urbanization.

Explanation of Symbols:

   1. An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations we
to compute a standard error and thus the margin of error. A statistical test is not appropriate.
   2. An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were avai
compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowe
upper interval of an open-ended distribution.
   3. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution.
   4. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution.
   5. An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open
distribution. A statistical test is not appropriate.
   6. An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variabil
appropriate.
   7. An 'N' entry in the estimate and margin of error columns indicates that data for this geographic area cannot be displayed b
number of sample cases is too small.
   8. An '(X)' means that the estimate is not applicable or not available.

Supporting documentation on code lists, subject definitions, data accuracy, and statistical testing can be found on the American
Community Survey website in the Data and Documentation section.

Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on the
American Community Survey website in the Methodology section.
Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, for 2010, the
2010 Census provides the official counts of the population and housing units for the nation, states, counties, cities and towns.
For 2006 to 2009, the Population Estimates Program provides intercensal estimates of the population for the nation, states, and
counties.

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from
sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error.
The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate
minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true
value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling
variability, see Accuracy of the Data). The effect of nonsampling error is not represented in these tables.
There were changes in the edit between 2009 and 2010 regarding Supplemental Security Income (SSI) and Social Security. The
changes in the edit loosened restrictions on disability requirements for receipt of SSI resulting in an increase in the total number
of SSI recipients in the American Community Survey. The changes also loosened restrictions on possible reported monthly
amounts in Social Security income resulting in higher Social Security aggregate amounts. These results more closely match
administrative counts compiled by the Social Security Administration.

Workers include members of the Armed Forces and civilians who were at work last week.

Industry codes are 4-digit codes and are based on the North American Industry Classification System 2007. The Industry
categories adhere to the guidelines issued in Clarification Memorandum No. 2, "NAICS Alternate Aggregation Structure for Use
By U.S. Statistical Agencies," issued by the Office of Management and Budget.

Occupation codes are 4-digit codes and are based on the Standard Occupational Classification (SOC) 2010. The 2010 Census
occupation codes were updated in accordance with the 2010 revision of the SOC. To allow for the creation of 2006-2010 and
2008-2010 tables, occupation data in the multiyear files (2006-2010 and 2008-2010) were recoded to 2010 Census occupation
codes. We recommend using caution when comparing data coded using 2010 Census occupation codes with data coded using
previous Census occupation codes. For more information on the Census occupation code changes, please visit our website at
http://www.census.gov/hhes/www/ioindex/.

While the 2006-2010 American Community Survey (ACS) data generally reflect the December 2009 Office of Management and
Budget (OMB) definitions of metropolitan and micropolitan statistical areas; in certain instances the names, codes, and
boundaries of the principal cities shown in ACS tables may differ from the OMB definitions due to differences in the effective
dates of the geographic entities.

Estimates of urban and rural population, housing units, and characteristics reflect boundaries of urban areas defined based on
Census 2000 data. Boundaries for urban areas have not been updated since Census 2000. As a result, data for urban and rural
areas from the ACS do not necessarily reflect the results of ongoing urbanization.

Explanation of Symbols:

   1. An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations
were available to compute a standard error and thus the margin of error. A statistical test is not appropriate.
   2. An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were
available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls
in the lowest interval or upper interval of an open-ended distribution.
   3. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution.
   4. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution.
   5. An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open
ended distribution. A statistical test is not appropriate.
   6. An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling
variability is not appropriate.
   7. An 'N' entry in the estimate and margin of error columns indicates that data for this geographic area cannot be displayed
because the number of sample cases is too small.
   8. An '(X)' means that the estimate is not applicable or not available.

Supporting documentation on code lists, subject definitions, data accuracy, and statistical testing can be found on the American
Community Survey website in the Data and Documentation section.

Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on the
American Community Survey website in the Methodology section.

Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, for 2010, the
2010 Census provides the official counts of the population and housing units for the nation, states, counties, cities and towns. Fo
2006 to 2009, the Population Estimates Program provides intercensal estimates of the population for the nation, states, and
counties.

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from
sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error.
The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate min
the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In
addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability,
see Accuracy of the Data). The effect of nonsampling error is not represented in these tables.

The 2009 and 2010 plumbing data for Puerto Rico will not be shown. Research indicates that the questions on plumbing facilitie
that were introduced in 2008 in the stateside American Community Survey and the 2008 Puerto Rico Community Survey may no
have been appropriate for Puerto Rico.

While the 2006-2010 American Community Survey (ACS) data generally reflect the December 2009 Office of Management and
Budget (OMB) definitions of metropolitan and micropolitan statistical areas; in certain instances the names, codes, and boundar
of the principal cities shown in ACS tables may differ from the OMB definitions due to differences in the effective dates of the
geographic entities.

Estimates of urban and rural population, housing units, and characteristics reflect boundaries of urban areas defined based on
Census 2000 data. Boundaries for urban areas have not been updated since Census 2000. As a result, data for urban and rural
areas from the ACS do not necessarily reflect the results of ongoing urbanization.

Explanation of Symbols:

   1. An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations wer
available to compute a standard error and thus the margin of error. A statistical test is not appropriate.
   2. An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were
available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls
the lowest interval or upper interval of an open-ended distribution.
   3. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution.
   4. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution.
   5. An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open
ended distribution. A statistical test is not appropriate.
   6. An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variabili
is not appropriate.
   7. An 'N' entry in the estimate and margin of error columns indicates that data for this geographic area cannot be displayed
because the number of sample cases is too small.
   8. An '(X)' means that the estimate is not applicable or not available.

Supporting documentation on code lists, subject definitions, data accuracy, and statistical testing can be found on the
American Community Survey website in the Data and Documentation section.

Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on
the American Community Survey website in the Methodology section.

Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, for
2010, the 2010 Census provides the official counts of the population and housing units for the nation, states, counties,
cities and towns. For 2006 to 2009, the Population Estimates Program provides intercensal estimates of the population
for the nation, states, and counties.

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising
from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent
margin of error. The margin of error can be interpreted roughly as providing a 90 percent probability that the interval
defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper
confidence bounds) contains the true value. In addition to sampling variability, the ACS

estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The
effect of nonsampling error is not represented in these tables.
For more information on understanding race and Hispanic origin data, please see the Census 2010 Brief entitled,
Overview of Race and Hispanic Origin: 2010, issued March 2011. (pdf format)

The ACS questions on Hispanic origin and race were revised in 2008 to make them consistent with the Census 2010
question wording. Any changes in estimates for 2008 and beyond may be due to demographic changes, as well as
factors including questionnaire changes, differences in ACS population controls, and methodological differences in the
population estimates, and therefore should be used with caution. For a summary of questionnaire changes see
http://www.census.gov/acs/www/methodology/questionnaire_changes/. For more information about changes in the
estimates see http://www.census.gov/population/www/socdemo/hispanic/reports.html.

While the 2006-2010 American Community Survey (ACS) data generally reflect the December 2009 Office of
Management and Budget (OMB) definitions of metropolitan and micropolitan statistical areas; in certain instances the
names, codes, and boundaries of the principal cities shown in ACS tables may differ from the OMB definitions due to
differences in the effective dates of the geographic entities.

Estimates of urban and rural population, housing units, and characteristics reflect boundaries of urban areas defined
based on Census 2000 data. Boundaries for urban areas have not been updated since Census 2000. As a result, data
for urban and rural areas from the ACS do not necessarily reflect the results of ongoing urbanization.

Explanation of Symbols:

   1. An '**' entry in the margin of error column indicates that either no sample observations or too few sample
observations were available to compute a standard error and thus the margin of error. A statistical test is not
appropriate.
   2. An '-' entry in the estimate column indicates that either no sample observations or too few sample observations
were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median
estimates falls in the lowest interval or upper interval of an open-ended distribution.
   3. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution.
   4. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution.
   5. An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of
an open-ended distribution. A statistical test is not appropriate.
   6. An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling
variability is not appropriate.
   7. An 'N' entry in the estimate and margin of error columns indicates that data for this geographic area cannot be
displayed because the number of sample cases is too small.
