Caveats:
1. Population and rates are labeled ‘Not Applicable’ when they include a subset of ages 85-100+ because populations are not
available for those ages. More information: http://wonder.cdc.gov/wonder/help/ucd.html#Ages 85-100.
2. Death rates are flagged as Unreliable when the rate is calculated with a numerator of 20 or less. More information:
http://wonder.cdc.gov/wonder/help/ucd.html#Unreliable.
3. Deaths of persons with Age “Not Stated” are included in “All” counts and rates, but are not distributed among age groups,
so are not included in age-specific counts, age-specific rates or in any age-adjusted rates. More information:
http://wonder.cdc.gov/wonder/help/ucd.html#Not Stated.
4. The population figures for year 2020 are bridged-race estimates of the July 1 resident population, from the Vintage 2020
postcensal series released by NCHS on September 22, 2021. The population figures for year 2019 are bridged-race estimates of the
July 1 resident population, from the Vintage 2019 postcensal series released by NCHS on July 9, 2020. The population figures for
year 2018 are bridged-race estimates of the July 1 resident population, from the Vintage 2018 postcensal series released by NCHS
on June 25, 2019. The population figures for year 2017 are bridged-race estimates of the July 1 resident population, from the
Vintage 2017 postcensal series released by NCHS on June 27, 2018. The population figures for year 2016 are bridged-race
estimates of the July 1 resident population, from the Vintage 2016 postcensal series released by NCHS on June 26, 2017. The
population figures for year 2015 are bridged-race estimates of the July 1 resident population, from the Vintage 2015 postcensal
series released by NCHS on June 28, 2016. The population figures for year 2014 are bridged-race estimates of the July 1 resident
population, from the Vintage 2014 postcensal series released by NCHS on June 30, 2015. The population figures for year 2013 are
bridged-race estimates of the July 1 resident population, from the Vintage 2013 postcensal series released by NCHS on June 26,
2014. The population figures for year 2012 are bridged-race estimates of the July 1 resident population, from the Vintage 2012
postcensal series released by NCHS on June 13, 2013. The population figures for year 2011 are bridged-race estimates of the July
1 resident population, from the Vintage 2011 postcensal series released by NCHS on July 18, 2012. Population figures for 2010
are April 1 Census counts. The population figures for years 2001 – 2009 are bridged-race estimates of the July 1 resident
population, from the revised intercensal county-level 2000 – 2009 series released by NCHS on October 26, 2012. Population
figures for 2000 are April 1 Census counts. Population figures for 1999 are from the 1990-1999 intercensal series of July 1
estimates. Population figures for the infant age groups are the number of live births.
Note: Rates and population
figures for years 2001 – 2009 differ slightly from previously published reports, due to use of the population estimates which
were available at the time of release.
5. The population figures used in the calculation of death rates for the age group ‘under 1 year’ are the estimates of the
resident population that is under one year of age. More information: http://wonder.cdc.gov/wonder/help/ucd.html#Age Group.
6. Beginning with the 2018 data, changes have been implemented that affect the counts for ICD-10 cause of death codes O00-O99
compared to previous practice. In addition, data for the cause of death codes O00-O99 for 2003 through 2017 reflect differences
in information available to individual states and probable errors. Caution should be used in interpreting these data. More
information can be found at: https://www.cdc.gov/nchs/maternal-mortality/.
7. On March 11, 2021, the 2019 mortality data on CDC WONDER was updated with the 2019 mortality data updated by NCHS on March 4,
2021 to include corrected information for residents of Texas affecting 5 records previously coded to cause code *U01.4,
Terrorism involving firearms (homicide). The underlying and multiple cause of death codes for 5 records were corrected in the
2019 data. Underlying and multiple cause of death codes for those 5 records were recoded to Assault (homicide) by other and
unspecified firearm discharge, ICD-10 code X95. The corrected final death records replaces the data released on December 22,
2020
8. Changes to cause of death classification affect reporting trends. More information:

4. The population figures for years 2022 and later are single-race estimates of the July 1 resident population, from the Vintage
2022 postcensal series released by the Census Bureau on June 22, 2023. The 2022 series is based on the Modified Blended Base
produced by the US Census Bureau in lieu of the April 1, 2020 decennial population count. The Modified Blended Base consists of
the blend of Vintage 2020 postcensal population estimates for April 1, 2020, 2020 Demographic Analysis Estimates, and 2020
Census data from the internal Census Edited File (CEF). The population figures for years 2021 are single-race estimates of the
July 1 resident population, based on the Blended Base produced by the US Census Bureau in lieu of the April 1, 2020 decennial
population count, from the Vintage 2021 postcensal series released by the Census Bureau on June 30, 2022. The population figures
for year 2020 are single-race estimates of the July 1 resident population, from the Vintage 2020 postcensal series based on
April 2010 Census, released by the Census Bureau on July 27, 2021. The population figures for year 2019 are single-race
estimates of the July 1 resident population, from the Vintage 2019 postcensal series based on April 2010 Census, released by the
Census Bureau on June 25, 2020. The population figures for year 2018 are single-race estimates of the July 1 resident
population, from the Vintage 2018 postcensal series based on April 2010 Census, released by the Census Bureau on June 20, 2019.

8. The U.S. – Mexico Border Regions distinguish between counties near the U.S. – Mexico border in the border states of Arizona,
California, New Mexico, and Texas, and other areas. To simplify the Border region analysis, two mutually exclusive regions
within the United States are available: 1) U.S. – Mexico Border Region (i.e., 44 counties within 100 kilometers (62 miles) of
the U.S. – Mexico border), and 2) the U.S. Non-Border Region with the remaining counties of the selected four border states. The
Border counties selection was based on the 1983 La Paz Agreement:
https://www.epa.gov/sites/production/files/2015-09/documents/lapazagreement.pdf.. (i.e., counties for each state which fall
within 100 kilometers of the Border). Statistics are also available by each of the USA border counties along the U.S.-Mexico
area.
