Why Is This Important?
The total fertility rate (TFR) is a useful and feasible measure of reproductive health. Trends in TFR may reflect the contributions of environmental exposures and other modifiable risk factors for decreased fertility. Lead and pesticides have been linked with decreased fertility in all people; there are also consistent associations between polychlorinated biphenyls (PCBs) and sperm motility. Neighborhood-level characteristics including social, economic, and environmental risk factors also contribute to fertility (CDC NEPHT Program, 2022). Individuals in their 20s and early 30s have the highest TFR. In 2020, non-Hispanic White persons had the lowest TFR (range 897.2 to 1,808.8), followed by non-Hispanic Black persons (range 939.4 to 2,855.5) and "other" persons (range 1,124.9 to 3,547.3). Hispanic persons had the highest TFR with a range of 1,110.2 to 3,361.6 (CDC NEPHT Program Data Explorer, 2023).

How the Measure is Calculated
Numerator:Sum of (age-specific fertility rates in 5-year age groups * 1,000) * 5
Denominator:Total number of women of reproductive age (15-44 years old)
Birth Certificate Data
Birth certificate information is submitted electronically by hospital medical records staff who use standard mother and facility worksheets and medical charts to collect the needed information. Training of hospital staff is provided by the Bureau of Vital Records and Health Statistics (BVRHS). The birth certificate information is reviewed by BVRHS for completeness and consistency with state law and NMDOH and national guidelines. BVRHS will contact hospital staff for clarification of missing, inconsistent or incorrect entries. CDC's National Center for Health Statistics provides feedback to BVRHS on data quality and the NMDOH provides feedback to the hospitals to improve data quality and training.
New Mexico Population Estimates
All population estimates apply to July 1 of the selected year. These estimates are considered the most accurate estimates for the state of New Mexico and should match those found on the University of New Mexico Geospatial and Population Studies website. Estimates include decimal fractions. Census tract population estimates were summed to produce County and Small Area population estimates. Population estimate totals may vary due to rounding. Population estimates for previous years are occasionally revised as new information becomes available. When publishing trend data, always be sure that your rates for earlier years match current rates on NM-IBIS that have been calculated with the most up-to-date population estimates.
