Where children are healthiest in the U.S. — and where they struggle most

About 94% of American children carry health insurance, but coverage alone isn't enough. Workers contribute an average of $6,850 per year toward employer-sponsored family health coverage, leaving millions of households exposed to out-of-pocket costs that erode access to care. States with weak coverage rates force families to absorb those costs directly, and insured children wait longer for care in states with limited pediatric workforces.

Children in states with low uninsured rates see a doctor regularly, catch preventable conditions early, and carry lower mortality risk into every year of childhood. Children in states with high uninsured rates skip those visits, accumulate untreated illness, and face higher emergency costs that push their families further from care. The two outcomes are not independent: each missed visit makes the next problem harder to treat, and each unpaid bill makes the next visit less likely. Where a child lives determines whether this cycle builds toward better health or away from it. In states where food access, pediatric availability, vaccination infrastructure, and insurance coverage are all present, children benefit from each one reinforcing the others. In states where those conditions are simultaneously absent, children face each disadvantage without the buffer the others would provide.

WalletHub ranked all 50 states and the District of Columbia on children's healthcare by analyzing 33 indicators across three dimensions: kids' health and access to healthcare, kids' nutrition, physical activity and obesity, and kids' oral health. Each state received an overall score and dimensional rankings, with a score of 100 representing the best possible conditions. The analysis captured outcomes ranging from infant mortality and vaccination rates to pediatrician availability and the share of children living near a recreation area.

Massachusetts holds the top overall score of 67.34, and its lead over the rest of the country rests on a near-complete absence of uninsured children. Only 1.6% of children in the state lack health insurance — the lowest rate of any state in the country. Coverage at that level drives routine care. Massachusetts ranks sixth in the share of children who received both a medical and a dental preventive care visit in the past 12 months.

Preventive care keeps serious conditions from developing, and Massachusetts' mortality figures prove it. The state posts the third-lowest infant mortality rate in the country and the second-lowest death rate for children ages 14 and under. These are not independent achievements. They stem from a healthcare system that intercepts risk early, connecting children to clinicians before conditions become emergencies. States with high uninsured rates produce the opposite pattern: children enter the healthcare system late, at higher cost, and with worse outcomes.

Nutrition reinforces the health picture. Massachusetts children consume soda at a lower rate than children in any other state, an eating pattern that supports oral health and reduces obesity risk simultaneously. The state ranks second for the lowest share of obese children ages 10 to 17. Massachusetts also holds the top spot nationally for the share of children with excellent or very good teeth, a figure that reflects both diet and the consistent preventive dental care that low uninsured rates make possible.

Massachusetts ranks fourth overall in kids' nutrition, physical activity, and obesity, meaning its strong performance extends beyond healthcare access. The state has built an environment where children are less likely to be overweight, more likely to see a doctor regularly, and more likely to survive infancy than children in nearly every other part of the country. Massachusetts ranks 14th in kids' oral health — its weakest dimension — but remains one of a small number of states to place in the top tier across all three scored dimensions.

Rhode Island ranks second overall with a total score of 61.77, and its most distinctive strength is cost protection for families. Only 6.5% of residents report trouble paying their children's medical bills — the second-lowest rate in the country. Hawaii ranks first on that metric, but Rhode Island closes the gap substantially on every other financial indicator, producing a state where healthcare costs impose less burden on households than almost anywhere else.

The state ranks sixth for the lowest percentage of uninsured children, which limits the population vulnerable to high out-of-pocket costs. Rhode Island also ranks eighth for the lowest out-of-pocket costs for children's healthcare. Even when parents do pay, they pay less than households in most other states. The state reinforces financial accessibility with the second-highest number of children's hospitals per capita, giving families physical proximity to specialized pediatric care when they need it.

Rhode Island's health outcomes reflect its access advantages directly. The state records one of the lowest death rates for children under age 14, and vaccination contributes a measurable share of that outcome. More than 80% of children ages 19 to 35 months have completed the combined seven-vaccine series, which protects against diphtheria, pertussis, tetanus, poliovirus, measles, mumps, rubella, hepatitis B, Haemophilus influenzae type b, varicella, and pneumococcal infections. States that maintain vaccination rates above 80% reduce the probability of outbreak-driven infant and child mortality, and Rhode Island's rate places it among the most comprehensively immunized young populations in the country.

Ranking fifth in kids' health and access to healthcare, the Ocean State sits just behind Connecticut in that dimension. Rhode Island ranks 17th in kids' oral health, a position in the top third of all states and one that rounds out a profile of consistent, above-average performance across every dimension the ranking measures.

Connecticut ranks third overall with a total score of 60.91, and its single most concrete achievement is the lowest death rate for children under age 14 of any state in the country. The state holds the fourth-lowest share of uninsured children — tied with the District of Columbia — placing it among the top five states for coverage and ensuring that the children who need care can access it without financial exclusion.

Vaccination coverage explains part of why Connecticut achieves that low mortality figure. The state posts the highest share of children ages 19 to 35 months who have received the combined seven-vaccine series, protecting a larger proportion of its youngest residents against preventable infectious diseases than any other state. Pediatrician and family doctor availability reinforces this: Connecticut holds a high number of these physicians per capita, reducing the distance between a child and a clinical visit.

Nutrition strengthens the foundation. Connecticut ranks 10th for the lowest share of children who eat fruits less than once per day, a figure that reflects both dietary behavior and the food environment the state sustains. The state ranks fifth in the country for healthy food access, meaning fewer children grow up in areas where nutritious options are scarce or geographically distant. Lower fast-food dependence and stronger nutrition infrastructure reduce the chronic disease burden that children carry into adulthood.

Connecticut's relative weakness sits in the oral health dimension, where it ranks 28th. Dental health carries five of the 100 possible scoring points, so this gap does not dislodge Connecticut from the third position overall. The state still posts a top-tier share of children with excellent or very good teeth, a figure that reflects access to the preventive dental visits that catch decay before it advances and places Connecticut well above the national midpoint on that measure.

Mississippi ranks 51st overall with a total score of 37.69, a position that reflects simultaneous last-place finishes across the widest range of child health conditions of any state in the country. Mississippi ranks 50th in kids' health and access to healthcare, 51st in kids' nutrition, physical activity, and obesity, and 49th in kids' oral health. No other state finishes in the bottom three of all three dimensions.

Infant mortality in Mississippi is the highest in the country. The gap between Mississippi's rate and New Hampshire's — the national best — spans a factor of three. Infant mortality at that level signals systemic failures in prenatal care, newborn health infrastructure, and the routine clinical access that catches complications before they prove fatal. Children in Mississippi do not enter the healthcare system under the same conditions as children in New England states. Mississippi's pediatric workforce ranks among the thinnest in the country, and hospital resources per child fall well below the levels found in top-ranked states.

The obesity figures extend that picture into childhood. Mississippi ties Arkansas for the highest percentage of overweight children ages 10 to 17 and ranks last for the proportion of obese children in that age group. Mississippi is the only state to appear at the bottom of both weight metrics simultaneously. The share of obese children in Mississippi is double the figure in Colorado, which ranks first on that metric. Children carrying excess weight at these rates face elevated long-term cardiovascular, metabolic, and orthopedic risk, and Mississippi's nutrition environment generates those conditions at higher rates than anywhere else in the country.

Oral health confirms the pattern across that dimension. Mississippi ranks 49th for the share of children with excellent or very good teeth and 51st — last in the country — for the share of children who received a recent medical and dental checkup. Children who miss regular preventive visits accumulate decay that compounds over time, and Mississippi's last-place finish on checkup rates identifies a population that is not reaching the clinical settings where early oral intervention occurs.

Arizona finishes 50th overall with a score of 41.36, and its defining deficiency sits in reported child health status. Arizona ranks 51st — last among all 50 states and the District of Columbia — for the share of children whose parents describe their health as excellent or very good. No other state records a lower share of children in strong perceived health, and that position captures the cumulative effect of Arizona's structural gaps.

Insurance access drives much of that shortfall. Arizona ranks 49th in uninsured children, and that means more skipped visits and untreated ailments. Coverage gaps reduce contact with clinicians, reduced contact allows problems to worsen, and worsening problems produce a population of children whose health parents describe as less than excellent or very good at a higher rate than anywhere else in the country.

Arizona ranks 41st in kids' nutrition, physical activity, and obesity, placing it in the bottom 12 states on a dimension that shapes long-term health from early childhood. Children in Arizona face above-average rates of poor dietary patterns and limited recreation access, conditions that contribute to higher obesity prevalence and reduce the nutritional foundation that healthy development requires.

The state's relative strength is in kids' oral health, where it ranks 27th nationally, near the midpoint on that dimension. Its 49th-place finish in health and access to healthcare, however, describes a state where children lack both sufficient coverage and the clinical infrastructure to convert coverage into regular, preventive care.

Alaska ranks 49th overall with a score of 42.20, and its most severe failure appears in infant mortality. The state records the second-highest infant death rate in the country, behind only Mississippi.

Insurance compounds the mortality risk, and Alaska, which ties Nevada for the 46th-worst uninsured rate among children, knows the situation all too well. Uninsured infants and young children miss the regular well-child visits where clinicians identify abnormal development, diagnose infections, administer vaccines, and screen for conditions that — treated early — carry far lower mortality risk. Low coverage and high infant mortality together describe a system where too many children never reach the clinical touchpoints that prevent early death.

Alaska ranks 50th in kids' nutrition, physical activity, and obesity, second to last in the country on that entire dimension. The state's geography limits food access for low-income residents, particularly in rural areas where the nearest supermarket, supercenter, or large grocery store lies more than 10 miles away. The healthy-food access metric captures that barrier directly, and Alaska's near-bottom position on nutrition reflects it. Children who cannot reach nutritious food reliably face higher obesity rates, micronutrient shortfalls, and the chronic conditions those gaps produce over time.

Ranking 41st in kids' oral health, the state closes out its profile with a bottom-tier position in every dimension the ranking evaluates. Its score reflects a child health environment where mortality, insurance coverage, nutrition access, and dental care all fall short at the same time. No single intervention closes that distance. Alaska's position across all three dimensions signals a structural deficit, not a targeted weakness in one area.
