Questions for Joyce A. Martin, M.P.H., Demographer, Statistician, and Lead Author on “Births in the United States, 2016.”

Q: How have birth rates changed in 2016 among different age groups?

JM: In general, births rates for women aged under 30 declined in 2016, whereas rates for women 30 and over rose. By age group, however, the change in rates changed differed considerably. The birth rates for teens aged 15-19 declined 9% from 2015 to 2016, whereas the rates declined 4% for women aged 20-24 and 2% for women aged 25-29. For women aged 30 and over, rate rose 1% for women aged 30-34, 2% for women aged 35-39, and 4% for women aged 40-44. As a result of the rise in the birth rate for older women, women aged 30–34 have for the first time in 2016 a higher birth rate than women aged 25–29.

Q: What did your report find on the trends for triplet and higher order multiple births?

JM: The rate of triplet and higher order multiple births was 101.4 per 100,000 total births in 2016, down 48% from the peak in 1998.

Q: Was there anything in the 2016 birth data that surprised you?

JM: The continued decline in birth rates among women under age 30 and the continued increase in the preterm birth rate which rose for the second straight year to 9.85% in 2016.  This rate had been on the decline from 2007 to 2014.

Q: What is the take home message from this report?

JM: The report documents a continuation of recent trends in several key birth measures in the United States.  Most notably, continued declines in childbearing among women under 30 years of age, continued declines in the cesarean delivery rate and increases in the preterm birth rate.

Q: When do you expect the Final 2016 Births report will be released?

JM: We expect the report to be released late this year or in early 2018.

Early Release of Selected Estimates Based on Data From the January – March 2017 National Health Interview Survey

September 21, 2017

Questions for Tina Norris, Ph.D., Health Statistician and Lead Author of “Early Release of Selected Estimates Based on Data From the January – March 2017 National Health Interview Survey.”

Q: Were there any findings that surprised you in this early release report?

TN: It is hard to say with quarter 1 findings that anything is truly “surprising” because estimates are based on a smaller sample sizes and could fluctuate a bit before settling down by the time we have a full year’s worth of data to analyze.

Q: Are there any trends in this report that Americans should be concerned about?

TN: Obesity is an epidemic that has seen a steady increase since 1997 and now affects just under one third (32.0%) of U.S. adults.

Q: Can you define what the health measure “usual place to go for medical care” means?

TN: Having a “usual place to go for medical care” is based on the question, “Is there a place that you usually go to when you are sick or need advice about your health?” If there was at least one such place, then a follow-up question was asked: “What kind of place [is it/do you go to most often]—a clinic, doctor’s office, emergency room, or some other place?” Adults who indicated that the emergency room was their usual place for care were considered not to have a usual place for health care.

Q: What do the findings in this report tell us about access to healthcare?

TN: Since 2010, the percentage of uninsured persons has decreased by almost 50% (16.0% vs 8.8%), and the percentage of persons who had a usual place to go for medical care increased from 85.4% in 2010, to 88.8% in January–March 2017. These two indicators demonstrate increased access to healthcare from 2010 through the first quarter of 2017.

Q: How do you collect your data for these surveys?

TN: The data is collected by household interview surveys that are fielded continuously throughout the year by the National Center for Health Statistics (NCHS). Interviews are conducted in respondents’ homes. Health and socio-demographic information is collected on each member of all families residing within a sampled household. Within each family, additional information is collected from one randomly selected adult (the “sample adult”) aged 18 years or older and one randomly selected child (the “sample child”) aged 17 years or younger. NHIS data is collected at one point in time so we cannot determine causation. Data presented in this report are quarterly data and are preliminary.
