Summary
South Dakota
Area of Science:
- Public Health
- Demographics
- Epidemiology
Background:
- South Dakota experienced a rise in births in 2024, with a diverse racial/ethnic composition.
- The state recorded the nation's highest birth and fertility rates in 2023.
- Recent trends show increasing birth contributions from non-White/American Indian populations.
Purpose of the Study:
- To analyze infant mortality trends in South Dakota.
- To investigate racial/ethnic disparities in birth rates and infant mortality.
- To examine the impact of sudden unexpected infant death (SUID) on overall mortality.
Main Methods:
- Analysis of 2024 birth data and demographic information.
- Comparison of South Dakota's 2023 birth and fertility rates with national data.
- Examination of 5-year (2020-2024) infant mortality data, stratified by race/ethnicity.
- Assessment of sudden unexpected infant death (SUID) rates and associated risk factors.
Main Results:
- The state's infant mortality rate (IMR) increased in 2024, with neonatal and post-neonatal increases noted in the White/Hispanic population.
- While White individuals constitute 71% of births, they account for 51% of infant deaths; American Indians (13% of births) account for 30% of infant deaths.
- Sudden unexpected infant death (SUID) accounts for 23% of infant deaths, with a statistically significant higher rate than the national average and increasing potentially preventable risks.
- The 2020-2024 overall IMR (7.03) and post-neonatal mortality rate (2.03) in South Dakota were significantly higher than national 2023 rates.
Conclusions:
- South Dakota faces significant challenges with increasing infant mortality, particularly among White/Hispanic and American Indian populations.
- Disparities in infant mortality persist, with disproportionately high contributions from minority groups.
- The elevated and non-decreasing rate of SUID, along with associated preventable risks, requires urgent public health intervention.

Population Growth
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...
Three Developmental Domains
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Oppositional Defiant Disorder
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Introduction to Developmental Psychology
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
