Introduction
Each year the Census Bureau provides bridged-race and unbridged population estimates by single-year
of age at the county level to the National Center for Health Statistics (NCHS) to meet programmatic
needs such as the creation of age groupings that differ from the standard groupings used by the
Census Bureau.
The Census Bureau itself does not release these bridged-race or unbridged estimates by single-year
of age at the county level due to concerns about the reliability of these estimates.
Because the Utah Department of Health and Human Services also requires age groupings that differ
from the standard groupings used by the Census Bureau, we decided to use the population estimates
that the Census Bureau develops for the NCHS.
Every year, the Census provides NCHS a July 1 postcensal estimate and revisions to previous
postcensal estimates back to the last census year. Therefore, we will be updating population
numbers on IBIS-Q back to the last census in approximately September of each year. The IBIS-Q
version numbers will refer to the Census Vintage year for the estimates and postcensal revisions.
The Census-NCHS population estimates were discontinued in 2021.
Kem C. Gardner Policy Institute intercensal estimates for years 2010 through 2019 incorporate 2020 decennial data.
Kem C. Gardner Policy Institute population estimates will be used in updating population numbers on IBIS-Q beginning with 2020 data and updated annually each year. The IBIS-Q version numbers will refer to the most current Kem C. Gardner Policy Institute population estimates.

the Utah Small Area numbers to sum to the county totals (minus round-off error), while
maintaining the sex and age group distributions in each Utah Small Area.
NOTE: In addition to updating existing Small Area population numbers, there were
changes to some of the Small Areas, and the addition of one new Small Area in 2012. (See:

State, County and Local Health District Resident Population Estimates
Year 2012
The estimates for 2012 on IBIS-Q were U.S. Census Bureau July 1, 2012 county-level total
population estimates. These were released by the Census Bureau in March 2013. We applied
the proportions by sex and single-year-of-age from the 2011 Vintage estimates (see below)
to the 2012 total county counts in order to impute the 2012 county estimates by sex and
single-year-of-age. These were added to IBIS-Q in May 2013. For more information please see:
http://www.census.gov/popest/data/counties/totals/2012/CO-EST2012-alldata.html
Effective dates: May 2013 to November 29, 2013
Years 2010-2011
The estimates for years 2010 and 2011 for counties by sex and single-year-of-age on IBIS-Q
are Vintage 2011 U.S. Census Bureau July 1 estimates based on the 2010 census counts. They
were produced by the Population Estimates Program of the U.S. Census Bureau in collaboration
with the National Center for Health Statistics (NCHS) and released on July 18, 2012. They
were included in IBIS-Q on November 30, 2012. For more information go to:
http://www.cdc.gov/nchs/nvss/bridged_race/data_documentation.htm#vintage2011
Effective dates: November 30, 2012 to May 16, 2013
Years 2000-2009
The 2000-2009 population estimates for counties by sex and single-year-of-age on IBIS-Q
are revised bridged-race intercensal estimates of the July 1 population based on both the
year 2000 and 2010 census counts. They were produced by the Population Estimates Program of
the U.S. Census Bureau in collaboration with the National Center for Health Statistics
(NCHS) and released by NCHS on October 26, 2012. They were included in IBIS-Q on
November 30, 2012. For more information go to:
http://www.cdc.gov/nchs/nvss/bridged_race/data_documentation.htm#july2009
Effective dates: November 30, 2012 to present
Years 1980-1999
The population estimates on IBIS-Q for counties by sex and single-year-of-age for years
1980-1999 are from the Utah Governor's Office of Planning and Budget (GOPB) in
collaboration with the Utah Population Estimates Committee (UPEC). They do not include
estimates by race or ethnicity. For more information go to:
http://www.governor.utah.gov/dea/demographics.html
Utah Small Area Resident Population Estimates
Year 2011
The Utah Small Area estimates for July 1, 2011 are based on the 2010 U.S. Census Bureau
April 1 Census ZIP Code population counts. We adjusted the counts from the April Census to
agree with the July 1 estimates for Utah counties from the National Center for Health
Statistics that were developed in collaboration with the U.S. Bureau of the Census. ZIP
Code-level estimates by sex and age group for 2011 were obtained from ESRI. The Utah Small
Area numbers were adjusted to sum to the county (minus round-off error), while maintaining
the sex and age group distributions in each Utah Small Area.
Effective dates: November 30, 2012 to November 29, 2013
Race and Ethnicity Resident Population Estimates
Years 2010-2011
The estimates for years 2010 and 2011 on IBIS-Q for counties by race and ethnicity are the
Vintage 2011 state and county resident population estimates by age, sex, race and Hispanic
origin from the U.S. Census Bureau based on the 2010 census counts. They were released in
June 2012. They were included in IBIS-Q on November 30, 2012. For more information go to:
http://www.census.gov/popest/methodology/2011-stco-char-meth.pdf
Effective dates: November 30, 2012 to November 29, 2013
Years 2000-2009
The estimates for years 2000-2009 are intercensal estimates of the resident population at
the county level as of July 1, 2000-July 1, 2009. They are based on the 2000 and 2010
censuses. They were produced by modifying the 2000-2009 postcensal estimates to account for
differences between the postcensal estimates for April 1, 2010 and 2010 Census counts. They
were released by the U.S. Census in October 2012 and were included in IBIS-Q on
November 30, 2012. For more information go to:

| History and Background of Population Estimates on IBIS-PH |
State and County Estimates
Utah population estimates have been available in Utah Department of Health and Human Services (DHHS) query
systems since 1994 with the development of ACTION2000 and continuing to the present in the
IBIS-PH Query System (IBIS-Q). The population estimates are used in other IBIS-Q modules for
the calculation of rates, including rates of cancer, hospitalizations, deaths, and births.
Initially, and until November 2012, the estimates for the state, counties, and local health
districts were from the Utah Governor's Office of Planning and Budget (GOPB: now the Governor's
Office of Management and Budget or GOMB). GOPB, in collaboration with the Utah Population
Estimates Committee (UPEC), developed estimates and projections for counties by sex and
single-year-of-age based on a model that differed from that used by the U.S. Census Bureau.
Specifically, the GOPB model utilized specialized local Utah information so that the estimates
were considered to be more accurate than those from the U.S. Census Bureau Population Estimates
Program. However, the GOPB decided to discontinue developing estimates for counties by sex and
single-year-of-age. And because some health indicator measures require the use of specialized
sex and age populations for denominators, the UDOH Center for Health Data and Informatics
decided to adopt estimates that the National Center for Health Statistics develops in
collaboration with the Population Estimates Program of the U.S. Census Bureau.
Utah Small Area Estimates
When DHHS staff developed Utah Small Areas in 1997, population estimates for the ZIP Code
areas were obtained from a commercial vendor and then adjusted to GOPB county estimates to
create Utah Small Area population estimates so that the Utah Small Areas within a county summed
to the county total. The Utah Small Area's sex by age group numbers were made to sum to the
county estimate and in the process were adjusted to have the same age and sex distribution as
the county. While revising the Utah Small Area estimates in November 2012 to agree with the
NCHS/U.S. Census estimates and revisions by county, DHHS staff decided that it would be more
appropriate to maintain the Utah Small Area age and sex distributions in the adjustment to
summing to the county estimates. Due to the different data sources, the county estimates which
result from summing across all Utah Small Areas within a county will not be an exact match with
the estimates from the NCHS/U.S. Census Bureau county-level data set.
Race and Ethnicity Resident Population Estimates
Population estimates by race and ethnicity in IBIS-PH have always been taken from the U.S.
Census Bureau Population Estimates Program, starting with year 2000, and available for counties
and local health districts. However, during the time that other Utah estimates were taken from
the GOPB, county and LHD totals from this data did not sum to GOPB numbers.
