Where you live in America determines when you’ll die
Two maps show two very different takes on the huge discrepancies in U.S. life expectancy
- These maps show strong links between location and life expectancy.
- Hawaiians live longest, Mississippians die earliest.
- County-level ranking shows short-life hotspots in Kentucky, long-life ones in Colorado.
High in Hawaii...

Tell me where you live, and I'll tell you how long you've got left. Fortunately, it's not quite that simple; but as these maps suggest, there is a strong link between location and average life expectancy.
Americans born in 2015 can expect to live to the age of 78.8 years. That's one-tenth of a year less than in 2014, the Centers for Disease Control (CDC) reported, and the first time U.S. life expectancy declined since 1993.
The CDC cited the rise of preventable deaths — notably traffic accidents (+6%) and "accidental poisonings" (+13%) as the main causes for the drop in longevity. The latter category consists almost entirely (97 percent) of alcohol and drug overdoses, with the opioid epidemic a major contributor to the increase.
... low in Mississippi

As these maps show, the national average tells only a small part of the story. The first one breaks down the national result in averages per state. It shows both huge disparities and regional similarities.
- Hawaii is the best-performing state. Newborns can expect to reach the ripe old age of 81.15 years. That puts the Aloha State on a par with Belgium (which according to the World Health Organisation had a life expectancy at birth of 81.1 years in 2015) and the U.K. (81.2 years) — countries placing 21st and 20th in the WHO world ranking.
- There's a gap of more than six years with Mississippi, the state with the lowest life expectancy in the Union: 74.91 years. That puts Mississippians on a par with Nicaraguans (74.8 years; 73rd in the WHO ranking) and the Lebanese (74.9 years; 70th).
- Living in the South is bad for your health: the 10 states with the lowest life expectancy form a single bloc centred on the southeast of the US.
- Mississippi (74.91 years)
- Alabama (75.65 years)
- Louisiana (75.82 years)
- West Virginia (76.03 years)
- Oklahoma (76.08 years)
- Arkansas (76.18 years)
- Kentucky (76.26 years)
- Tennessee (76.33 years)
- South Carolina (76.89 years)
- Georgia (77.38 years)
There's a similar bloc in the northeast, but on the other end of the scale: here, six of the 10 best-performing states congregate.
- Hawaii (81.15 years)
- California (80.92 years)
- Minnesota (80.90 years)
- Connecticut (80.56 years)
- Massachusetts (80.41 years)
- New York (80.36 years)
- Vermont (80.24 years)
- Colorado (80.21 years)
- New Hampshire (80.15 years)
- New Jersey (80.04 years)
In some counties, longevity is a two decades' difference

By focusing on counties rather than states, the second map throws new light on the subject. The top 20 and bottom 20 counties cluster in a very different pattern.
For one, Hawaii, the best performer at state level, has no county-level representatives. Two: Mississippi, the worst-performing state, has only three of the 20 worst-performing counties. Yet half of the bottom-20 counties can be found in two other states.
- No less than six of the bottom-20 counties are in Kentucky, in a zone of low life expectancy adjoining West Virginia, home to two more worst-performing counties.
- Four are in South Dakota, including Oglala Lakota County, the county with the lowest life expectancy in the country, at just 66.81 years. That's on a par with Senegal (128th on the WHO ranking). This despite the fact that overall, South Dakota is doing pretty well (79.57 years on average).
Poverty and longevity

The counties in the Dakotas with low life expectancy are contiguous with Native-American reservations, which suffer from extreme levels of poverty and addiction. Oglala Lakota County (Shannon County until it was renamed in 2015) is contained entirely within the Pine Ridge Indian Reservation.
Also in that reservation (but in neighbouring Bennett County) is the town of Allen, the poorest place in the United States. As of the 2000 census, more than 95 percent of its 419 inhabitants lived below the poverty line. Allen is located near North America's continental pole of inaccessibility (at 43°21'36" N, 101°58'12" W): 1024 miles (1650 km) from the nearest coastline.
Colorado contains the top-three counties (highest life expectancy: Summit County, 88.83 years), and three more from the top 20. One theory explaining Colorado's high scores is that the state is a popular destination for people who love the outdoors; so it's not that living in Colorado makes you live longer per se, it's that people with healthier lifestyles move to Colorado.
There are two smaller long-life clusters: in the Bay Area and in northern Virginia, each with three counties in the top 20.
Long live Colorado

Three states have counties in both categories.
- The average Alaskan in the Kusilvak Census Area never makes it to their 71st birthday. A bit further south, in either the Aleutians East Borough or the Aleutians West Census Area, they would get to blow out 83 candles before expiring.
- The average inhabitant of Billings County, North Dakota makes it just past their 84th birthday. That's the fourth-best score in the country. Nearby Sioux County has the country's fourth-worst score: 68.59 years.
- Residents of Union Country only get to be 67.57 years, on average, while their fellow Floridians in Collier County make it to 83.43 years — a difference of more than a decade and a half.
Not since the Spanish Flu

The national average quoted on the first map dates from 2015. More recent CDC data shows the decline continued in 2016 (to 78.7 years) and 2017 (to 78.6 years). The only other three-year drop in life expectancy registered in CDC records (which go back to 1900) dates from the second half of the 1910s, when the World War and the Spanish Flu caused life expectancy to drop from 54.5 years in 1915 to just 39.1 years in 1919 — the lowest average life expectancy on record.
The figures also show separate results for race and gender, and huge disparities between them. Whites do better than blacks, and women outlive men.
- White women reached an average life expectancy of more than 50 years in 1901, 60 years in 1921, 70 years in 1946 and 80 years in 1998. White men hit 50 in 1902, 60 in 1921 and 70 in 1977.
- The average life expectancy of black women exceeded 50 only in 1921. It reached 60 in 1946 and 70 in 1974. Black males averaged 50 years or more in 1921, 60 years in 1954 and 70 only from 2007.
Update 30 March: as reader Elizabeth Batson points out, there is a strong correlation between this map and one she recently saw on the CDC website on the prevalence of adult obesity, "especially on the high fat/short life side."

A new study finds that dogs fed fresh human-grade food don't need to eat—or do their business—as much.
- Most dogs eat a diet that's primarily kibble.
- When fed a fresh-food diet, however, they don't need to consume as much.
- Dogs on fresh-food diets have healthier gut biomes.
Four diets were tested<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTU5ODI1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NjY0NjIxMn0._w0k-qFOC86AqmtPHJBK_i-9F5oVyVYsYtUrdvfUxWQ/img.jpg?width=980" id="1b1e4" class="rm-shortcode" data-rm-shortcode-id="87937436a81c700a8ab3b1d763354843" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="960" />

The <a href="https://frontierpets.com.au/blogs/news/how-kibble-or-dry-dog-food-is-made" target="_blank">ingredients</a> of kibble are mashed into a dough and then extruded, forced through a die of some kind into the desired shape — think a <a href="https://en.wikipedia.org/wiki/Food_extrusion" target="_blank">pasta maker</a>. The resulting pellets are sprayed with additional flavor and color.</p><p>For four weeks, researchers fed 12 beagles one of four diets:</p><ol><li>a extruded diet — Blue Buffalo Chicken and Brown Rice Recipe</li><li>a fresh refrigerated diet — Freshpet Roasted Meals Tender Chicken Recipe</li><li>a fresh diet — JustFoodforDogs Beef & Russet Potato Recipe</li><li>another fresh diet — JustFoodforDogs Chicken & White Rice Recipe.</li></ol><p>The two fresh diets contained minimally processed beef, chicken, broccoli, rice, carrots, and various food chunks in a canine casserole of sorts. </p><p>(One can't help but think how hard it would be to get finicky cats to test new diets. As if.)</p><p>Senior author <a href="https://ansc.illinois.edu/directory/ksswanso" target="_blank" rel="noopener noreferrer">Kelly S. Swanson</a> of U of I's Department of Animal Sciences and the Division of Nutritional Sciences, was a bit surprised at how much better dogs did on people food than even refrigerated dog chow. "Based on past research we've conducted I'm not surprised with the results when feeding human-grade compared to an extruded dry diet," he <a href="https://aces.illinois.edu/news/feed-fido-fresh-human-grade-dog-food-scoop-less-poop" target="_blank">says</a>, adding, "However, I did not expect to see how well the human-grade fresh food performed, even compared to a fresh commercial processed brand."</p>

Credit: Patryk Kosmider/Adobe Stock<p>The researchers tracked the dogs' weights and analyzed the microbiota in their fecal matter.</p><p>It turned out that the dogs on kibble had to eat more to maintain their body weight. This resulted in their producing 1.5 to 2.9 times the amount of poop produced by dogs on the fresh diets.</p><p>Says Swanson, "This is consistent with a 2019 National Institute of Health study in humans that found people eating a fresh whole food diet consumed on average 500 less calories per day, and reported being more satisfied, than people eating a more processed diet."</p><p>Maybe even more interesting was the effect of fresh food on the gut biome. Though there remains much we don't yet know about microbiota, it was nonetheless the case that the microbial communities found in fresh-food poo was different.</p><p>"Because a healthy gut means a healthy mutt," says Swanson, "fecal microbial and metabolite profiles are important readouts of diet assessment. As we have shown in <a href="https://academic.oup.com/jas/article/92/9/3781/4702209#110855647" target="_blank">previous studies</a>, the fecal microbial communities of healthy dogs fed fresh diets were different than those fed kibble. These unique microbial profiles were likely due to differences in diet processing, ingredient source, and the concentration and type of dietary fibers, proteins, and fats that are known to influence what is digested by the dog and what reaches the colon for fermentation."</p>
How did kibble take over canine diets?<p>Historically, dogs ate scraps left over by humans. It has only been <a href="https://www.thefarmersdog.com/digest/the-history-of-commercial-pet-food-a-great-american-marketing-story/" target="_blank">since 1870</a>, with the arrival of the luxe Spratt's Meat Fibrine Dog Cakes—made from "the dried unsalted gelatinous parts of Prairie Beef", mmm—that commercial dog food began to take hold. Dog bone-shaped biscuits first appeared in 1907. Ken-L Ration dates from 1922. Kibble was first extruded in 1956. Pet food had become a great way to turn <a href="https://www.dogfoodadvisor.com/choosing-dog-food/animal-by-products/" target="_blank">human-food waste</a> into profit.</p><p>Commercial dog food became the norm for most household canines only after a massive marketing campaign led by a group of dog-food industry lobbyists called the Pet Food Institute in 1964. Over time, for most households, dog food was what dogs ate — what else? Human food? These days more than half of U.S. dogs are <a href="https://www.nytimes.com/2014/08/03/magazine/who-made-that-dog-biscuit.html" target="_blank">overweight or obese</a>, and certainly their diet is a factor.<span></span></p><p>We're not so special among animals after all. If something's healthy for us to eat—we're <em>not</em> looking at you, chocolate—maybe we should remember to share with our canine compatriots. Not from the table, though.</p>
What makes some people more likely to shiver than others?
Some people just aren't bothered by the cold, no matter how low the temperature dips. And the reason for this may be in a person's genes.
Eating veggies is good for you. Now we can stop debating how much we should eat.
- A massive new study confirms that five servings of fruit and veggies a day can lower the risk of death.
- The maximum benefit is found at two servings of fruit and three of veggies—anything more offers no extra benefit according to the researchers.
- Not all fruits and veggies are equal. Leafy greens are better for you than starchy corn and potatoes.
