Indicator-Based Information System for Public Health (IBIS-PH) Query System Population Estimates

Contents:


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 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.

Utah Small Area Resident Population Estimates


    Years 2011-2015

    The Utah Small Area population estimates for July 1, 2011 and July 1, 2015 on IBIS-Q were revised on September 16, 2016 to reflect updated Vintage 2015 postcensal estimates for July 1, 2015, July 1, 2012 and July 1, 2011 from the U.S. Census Bureau. The ZIP Code-level numbers by sex and single-year-of-age were from 2011, 2012, 2013, 2014 and 2015 ESRI data estimates. We then adjusted 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: http://ibis.health.utah.gov/pdf/resource/SAChangeSummary.pdf in the IBIS-PH Help section under 'Utah Small Areas' for more information about the changes in Utah's Small Areas.)

    Year 2010

    The Utah Small Areas population estimates for July 1, 2010 on IBIS-Q are based on the 2010 April 1 Census ZIP Code population counts. We adjusted the counts from the April Census to agree with the Vintage 2012 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. We then adjusted the Utah Small Area numbers to sum to the county (minus round-off error), while maintaining the sex and age group distributions in each Utah Small Area.

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



    Year 2010

    The estimates for July 1, 2010 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 2010 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



    Years 2005-2009

    The estimates for July 1, 2005 thru July 1, 2009 are based on the 2000 and 2010 U.S. Census Bureau April 1 Census ZIP Code population counts. We adjusted the counts from the April Censuses to agree with the revised intercensal 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 2005 were obtained from ESRI with an endpoint projection to 2009. So the 2006-2008 estimates were developed as linear extrapolations. 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 present for the 2005 data

    November 30, 2012 to October 16, 2013 for the 2006-2009 data



    Years 2000-2004

    The Utah Small Area population estimates on IBIS-Q for July 1, 2000 thru July 1, 2004 are based on the 2000 and 2010 U.S. Census Bureau April 1 Census ZIP Code population counts. We adjusted the counts from the April Censuses to agree with the revised intercensal 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 2005 were obtained from ESRI. The estimates for Utah Small Areas for 2001-2004 were created by linear extrapolation between the 2000 counts and the 2005 ESRI estimates by sex and age group in each Utah Small Area. 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 present



    Years 1990-1999

    The estimates for July 1 of years 1990-1999 are based on the 1990 and 2000 U.S. Census Bureau April 1 Census ZIP Code population counts. We adjusted the counts from the April Censuses to agree with the July 1 estimates for Utah counties developed by the Utah Governor's Office of Planning and Budget (GOPB) and the Utah Population Estimates Committee (UPEC). When the Utah Small Areas were developed in 1997, ZIP Code-level population estimates by sex and age group were purchased from CACI Marketing Systems for year 1997. The CACI file also included estimates for the average annual rate of population change for each ZIP Code and this information was used to derive the 1991-1999 population estimates. 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 present




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: http://www.census.gov/popest/methodology/2000-2010_Intercensal_Estimates_Methodology.pdf

History and Background of Population Estimates on IBIS-PH

State and County Estimates


    Utah population estimates have been available in Utah Department of Health (UDOH) 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 UDOH 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, UDOH 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.
