QuickStats: Rates of Deaths Attributed to Unintentional Injury from Fire or Flames by Age Group and Urbanization Level

August 28, 2020

In 2018, the death rates attributed to unintentional injury from fire or flames were lowest among those aged 15–24 years and highest among those aged 75 years or older.

In rural areas, death rates decreased with age from 2.0 per 100,000 for persons aged 0–4 years to 0.3 for those aged 15–24 years, and then increased with age to 5.6 for those aged 75 years or older.

The pattern was similar for urban areas, where rates were 0.5 per 100,000 for persons aged 0–4 years, decreased to 0.1 for those aged 15–24 years, and then increased with age to 2.8 for those aged 75 years or older.

Across all age groups, death rates were approximately two to four times higher in rural areas compared with urban areas.

Prevalence of Children Aged 3–17 Years With Developmental Disabilities, by Urbanicity: United States, 2015–2018

February 19, 2020

Questions for Ben Zablotsky, Ph.D., Health Statistician and Lead Author of “Prevalence of Children Aged 3–17 Years With Developmental Disabilities, by Urbanicity: United States, 2015–2018.”

Q: Why did you decide to focus on urbanicity among children with developmental disabilities?

BZ: Thanks to previous research, we know that children with developmental disabilities typically require more health care and educational services than their typically developing peers, and we also know that children living in rural areas have greater unmet medical needs when compared to children living in urban areas.  For these two reasons, it is possible, that children with developmental disabilities living in rural areas could represent some of the most vulnerable when it comes to receiving a variety of health care services.  This report attempts to answer this question, by exploring the prevalence of selected developmental disability conditions and use of related services in rural and urban areas.  It serves as a follow-up to a previous Pediatrics article written by myself and Lindsey Black, along with colleagues from the National Center for Health Statistics, National Center on Birth Defects and Developmental Disabilities, and the Maternal and Child Health Bureau, titled “Prevalence and Trends of Developmental Disabilities among Children in the United States: 2009-2017


Q: How did you obtain this data for this report and what is considered a developmental disability?

BZ: Data come from the 2015-2018 National Health Interview Survey, a timely and nationally representative survey.  Developmental disabilities examined in this report were attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, blindness, cerebral palsy, moderate to profound hearing loss, learning disability, intellectual disability, seizures in the past 12 months, stuttering or stammering in the past 12 months, or any other developmental delay. Children whose parents answered that their child had one or more of these conditions were classified as having any “developmental disability.”


Q: Can you summarize how the data varied by types of developmental disabilities and service utilization in rural and urban areas?

BZ: During 2015-2018, children were more likely to be diagnosed with ADHD and cerebral palsy in rural areas than urban areas.  Meanwhile, children with developmental disabilities living in rural areas were less likely to have seen a mental health professional, therapist, or had a well-child check-up in the past 12 months than their urban peers.  Children with developmental disabilities in rural areas were also less likely to be receiving Special Education or Early Intervention Services.


Q: Was there a specific finding in the data that surprised you?

BZ: Children with developmental disabilities often need specialty and mental health services.  It was surprising to see that approximately half of children with developmental disabilities living in rural areas had not seen a mental health professional, specialist, or therapist in the past year.


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

BZ: There was a higher prevalence of children with developmental disabilities in rural areas compared with urban areas. Furthermore, among children with developmental disabilities, those living in rural areas were less likely to use a range of health care and educational services compared with their urban peers.  Additional research exploring the pathways to the diagnosis and treatment of developmental disabilities in both urban and rural areas, with a focus on the availability of resources to pay for services as well as access to trained specialty providers, could provide insight into the disparities seen in this report.

Trends in Fertility and Mother’s Age at First Birth Among Rural and Metropolitan Counties: United States, 2007–2017

October 17, 2018

Questions for Danielle Ely, Health Statistician and Lead Author of “Trends in Fertility and Mother’s Age at First Birth Among Rural and Metropolitan Counties: United States, 2007–2017

Q: Why did you decide to look at fertility rates and mother’s age at first birth among rural and metropolitan U.S. counties?

DE: Rural and metropolitan counties have a variety of differences related to general health, birth outcomes, and mortality rates. However, we noticed that recent research did not focus on the overall fertility differences in these areas or maternal age, which can affect birth outcomes. Looking at these items can help us understand why we might see differences between rural and metro counties in births and birth outcomes.


Q: How did the findings vary by race?

DE: Patterns for total fertility rates were similar by race and Hispanic origin. There were higher total fertility rates in rural counties than in metropolitan counties among the three race and Hispanic origin groups in 2007. In 2017, this pattern was the same for non-Hispanic white and Hispanic women, but non-Hispanic black women had higher total fertility rates in small or medium metro counties compared with rural and large metro counties. Hispanic women had the highest total fertility rates for each urbanization level in both 2007 and 2017

Non-Hispanic white, non-Hispanic black and Hispanic women had lower ages at first birth in rural counties compared with both metro county types. This was true in both 2007 and 2017, and differences between county types widened over this time.


Q: How did the findings vary by mean age of mothers at first birth?

DE: Mean age at first birth was lower in rural counties than small or medium metro counties and large metro counties from 2007-2017. Each of the three race and Hispanic origin groups had lower mean age at first birth in rural counties compared with metropolitan counties.


Q: Is there any comparable trend data prior to 2007?

DE: We have not computed trend data on total fertility rates or mean age at first birth by urbanization level prior to 2007.


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

DE: The important message in this report is that there are differences in the fertility rates and mean age at first birth between rural and metro areas, and these differences have gotten larger over time. These trends are generally the same by race and Hispanic origin. Information on differences in birth rates and maternal age by urbanization level can inform decisions on resource allocation and ultimately lead to improvement in infant and maternal health.


Differences Between Rural and Urban Areas in Mortality Rates for the Leading Causes of Infant Death: United States, 2013–2015

February 15, 2018

Questions for Danielle Ely, Ph.D., “Differences Between Rural and Urban Areas in Mortality Rates for the Leading Causes of Infant Death: United States, 2013–2015

Q: Why did you decide to examine differences in mortality rates for the leading causes of infant death between rural and urban areas in the United States?

DE: After finding differences in infant mortality rates between rural and urban places in previous work, we thought causes of death might also differ by urbanization level. Although previous research looked at infant mortality rates by age of death and residence, there had not been research on leading causes of infant death by rural-urban status.


Q: Can you describe the differences in infant, neonatal, and postneonatal mortality rates?

DE: Infant mortality rates are based on all infant deaths. Neonatal mortality specifies the infant was less than 28 days of age at time of death and postneonatal mortality rates are those infant deaths that occurred between 28 days and 11 months of age. In this data brief, as in previous research, we see higher neonatal mortality rates than postneonatal mortality rates. Indeed, neonatal mortality rates were nearly twice as high as postneonatal mortality rates across urbanization levels. Further, there are distinct differences in the leading causes of death for neonatal and postneonatal mortality. Although both include congenital malformations, neonatal deaths are generally associated with more birth related medical issues whereas postneonatal deaths are generally associated with more causes external from the infant.


Q: Overall, how did the mortality rate for the five leading causes of infant death vary by urbanization level?

DE: Rural areas have higher infant, neonatal, and postneonatal mortality rates than urban areas. However, when we drill down by the leading causes of death by age of death, there are specific causes of death where infants in rural areas do experience lower mortality rates, such as mortality from low birthweight and from maternal complications. However, there are markedly higher mortality rates for both neonatal and postneonatal infants from congenital malformations, sudden infant death syndrome, and unintentional injuries in rural places than in urban.


Q: Were there any surprises in the findings from this report?

DE: Although we expected differences in mortality rates by the leading causes of death, I think we were surprised by the marked differences for some causes; particularly SIDS mortality rates being twice as high in rural places than in large urban counties. I also think some of the most interesting findings in the report are related to how rural infant mortality rates are generally higher than rates in urban areas, but there are some causes for which rural places have similar or even lower rates compared to urban places.


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

DE: The message that should be taken from this report is that different types of places– rural and urban– have different issues when it comes to the leading causes of infant death. Although the leading causes are generally the same across areas, there are substantial differences in rates, meaning different public health interventions may be needed for people in rural areas compared to people in urban areas to address these issues.


QuickStats: Infant Mortality Rate, by Urbanization Level — National Vital Statistics System, United States, 2007 and 2015

October 20, 2017

In both 2007 and 2015, infant mortality rates were highest in rural counties (7.5 infant deaths per 1,000 live births and 6.8, respectively).

Rates were lower in small and medium urban counties (7.1 in 2007 and 6.4 in 2015) and lowest in large urban counties (6.4 in 2007 and 5.4 in 2015).

For all three urbanization levels, infant mortality rates were significantly lower in 2015, compared with rates in 2007.

Infant Mortality Rates in Rural and Urban Areas in the United States, 2014

September 6, 2017

Questions for Danielle Ely, Ph.D., Statistician and Lead Author of “Infant Mortality Rates in Rural and Urban Areas in the United States, 2014

Q: What is the most significant finding in your study?

DE: The most significant finding in this study was the consistency with which infants in rural areas have significantly higher mortality rates than infants in urban places. Higher rural infant mortality was generally observed by race and Hispanic origin, mother’s age, and by infant age at death.


Q: Why are infant mortality rates higher in rural areas vs urban areas?

DE: Generally, previous research shows that health outcomes are poorer in rural places compared with urban places and this study is consistent with those findings. This study did not examine the factors that might be influencing the higher rural infant mortality in comparison with urban infant mortality.


Q: Is this surprising, or are problems with poverty, substance abuse, and health care that much worse in rural areas?

DE: Higher infant mortality in rural places compared with urban places is not necessarily surprising based on the number of other poor health outcomes (such as higher overall mortality rates, higher rates of disability) that rural residents have in comparison to urban residents.


Q: Are there any theories in the literature as to why this infant mortality disparity exists between rural and urban?

DE: Given there are some poorer health outcomes in rural areas, it is possible more pregnant women in rural areas have poorer general health than pregnant women in urban areas that can lead to poor infant outcomes. Further, there is generally less access to health care due to distance and number of providers available in rural areas, which can impact health outcomes.


Q: Any other findings of note that you find significant?

DE: These findings highlight the importance of place for infant survival and suggests the need for including place in research on health outcomes, as well as a need for further research on the greater risk of infant death in rural settings.


Teen Birth Rates for Urban and Rural Areas in the United States, 2007–2015

November 16, 2016

Questions for Brady Hamilton, Statistician and Lead Author of “Teen Birth Rates for Urban and Rural Areas in the United States, 2007–2015

Q: Are teen birth rates in the U.S. higher in urban areas or rural areas?

BH: The birth rate for teenagers is higher in rural areas than in urban areas. In 2015, the rate was 30.9 births per 1,000 females aged 15-19 for rural areas compared with 20.9 for urban areas. This difference persisted over the duration of the study, from 2007 through 2015, and was seen in the teen birth rates for non-Hispanic white, non-Hispanic black, and Hispanic females.


Q: What explains the differences or similarities in the two areas?

BH: The data on which the report is based comes from the birth certificates filed in all states and DC. While the data from the birth certificate provide detailed information on a number of topics, this report did not examine reasons for urban/rural differences, as information on many contributing factors is not available from the birth certificate.

However, the report shows that while the birth rate for teenagers is higher in rural areas than in urban areas, birth rates for all areas declined from 2007 through 2015, down 50% in large urban, 44% in medium and small urban, and 37% in rural areas.


Q: What were some of the regional differences you observed in teen birth rates in urban or rural areas?

BH: The urban teen birth rate declined for all states and DC between 2007 and 2015, with declines ranging from 24% for teens in North Dakota to 57% for teens in Arizona, whereas the rural teen birth rate declined for in nearly all states, with declines ranging from 18% for teens in Alaska to 73% for teens in Connecticut.

Among the urban areas, states with the largest declines (50% or more in the teen birth rate) include: Arizona, California, Colorado, Connecticut, Florida, Georgia, Maryland, Massachusetts, Minnesota, Mississippi, New Jersey, New Mexico, North Carolina, Rhode Island, Utah, Vermont, and Virginia.

Among the rural areas, states with the largest declines (50% or more in the teen birth rate) include: Colorado and Connecticut.


Q: Are there any data which suggests sexual activity among teens is higher in urban vs. rural areas – or vice versa?

BH: As noted, information is not available from the birth certificate on the attitudes and behavior of the parents associated with fertility and family formation.


Q: What are the differences in teen birth rates among race/ethnic groups and are there different patterns among these groups depending on whether they live in urban or rural areas?

BH: Teen birth rates for non-Hispanic white, non-Hispanic black, and Hispanic females were highest in rural counties and lowest in large urban areas in 2015.

For each area, the teen birth rate was consistently highest for Hispanic females and consistently lowest for non-Hispanic white females.

The difference in the teen birth rate between rural and large urban areas was lowest for non-Hispanic black females and greatest for non-Hispanic white females.

Q: Which U.S. counties have the highest teen birth rate and which counties have the lowest?

A: Teen birth rates are not available for individual counties in the report. Counties are grouped into areas according to their urban or rural designation and the teen birth rate was reported for an area based on the aggregated data of the counties for the area.
