Lifestyle

Your daily habits, benchmarked against everyone else's

Daily habits feel intensely private until somebody puts a number on them. Almost everyone believes their drinking is heavier than it is, their caffeine intake excessive, their screen time uniquely bad, their sleep schedule odd, their crying either far too frequent or not frequent enough. The data usually disagrees. NHANES, NIAAA, the NHS, Pew Research and Common Sense Media collect habit-level data on millions of adults every year, and the same pattern keeps appearing: people sit closer to the median than they fear on the things that worry them, and further from it on the things they assume are ordinary. These tools turn your everyday behaviour into a position on that curve. All of them are free, and every data source is named on the page.

Common Questions

01 What is a normal weekly alcohol intake?

It depends which guideline you trust, and the two big ones disagree. The NIAAA calls up to 14 drinks a week low-risk for men and up to 7 for women, with no more than 4 or 3 respectively on any single day. The NHS is stricter and applies one number to both sexes: up to 14 units a week, spread across at least three days. Unit sizes differ too, because a US standard drink is 14 grams of alcohol and a UK unit is 8, so the same beer counts as 1 US drink and 2 UK units. The heaviest 10 percent get through more than half of all the alcohol sold. The alcohol consumption calculator shows your weekly units against the NHS limits and the population distribution, with both conversions built in.

02 What is the average daily caffeine intake?

About 165 milligrams a day for the average US adult in NHANES data, though coffee drinkers specifically average nearer 280. The FDA treats up to 400 milligrams a day as generally safe for healthy adults, with tolerance moving a long way on genetics, sleep and pregnancy status. For scale, an 8oz cup of brewed coffee holds 80 to 100 milligrams, a Starbucks grande latte around 150, a 12oz can of Coke 35, and energy drinks run from 80 in a small Red Bull to over 300 in a large can of certain pre-workout mixes. Under-25s take less than 35 to 64 year olds, because tea and coffee habits build with age. Pregnancy guidelines cut the threshold to 200 milligrams, the equivalent of two 8oz coffees, and plenty of obstetricians go lower again. The caffeine consumption calculator totals your day across drinks and supplements and places you against the NHANES distribution.

03 What percentage of people have tattoos?

Roughly 32 percent of US adults have at least one on Pew Research 2023 figures, rising to 41 percent among under-30s. Women now outpace men, at 38 percent against 27. UK numbers run lower, at around 26 percent of adults per YouGov. Among tattooed adults the median count is 3 to 4, about half have at least one visible tattoo, and roughly 25 percent regret at least one of them. Removing a single small tattoo by laser typically costs $1,500 to $4,000 across 6 to 12 sessions, which is more than most originals cost to get. The tattoo count calculator places your count in the distribution by age and sex, and the tattoo meanings tool covers prevalence for the commonest designs (semicolon, butterfly, snake, lotus, 444).

04 Is it normal to cry a lot?

Almost certainly, because the variation between individuals is enormous. The International Study on Adult Crying, run across 37 countries, found women reporting more crying than men in nearly every country. No clinical threshold for too much exists outside the major depression criteria, where persistent tearfulness is one symptom among several. Hormonal cycles, antidepressants, recent grief, sleep debt and pregnancy all move the number a long way. Crying is social as well: people who cry with someone else report more mood improvement than people who cry alone, which cuts against the assumption that crying in front of others costs you something. Women in the US, UK and Sweden report crying more often than women in Bulgaria or Ghana, which says as much about cultural permission to report it as about the tears. The crying frequency calculator places your monthly count against the distribution by sex and age, and links on to deeper screeners if the frequency is distressing you.

05 What generation am I, and what does the data say about my cohort?

Pew Research's boundaries are the ones most people use: Silent (1928 to 1945), Boomer (1946 to 1964), Gen X (1965 to 1980), Millennial (1981 to 1996), Gen Z (1997 to 2012), and the still-unsettled Gen Alpha from 2013 onward. Pew itself has stepped back from rigid generational labelling, because the boundaries are arbitrary and the variance inside any one cohort dwarfs the difference between cohorts. Real effects do survive that caveat. Gen Z reports the lowest alcohol consumption of any generation in 50 years and the highest social anxiety. Gen X is the smallest US generation by population, and Boomers hold roughly half of all US household wealth while making up under 21 percent of it. People born within 2 years of a boundary usually identify with whichever cohort matches their cultural reference points rather than the technical year of birth. The what generation am I tool places you in a cohort and surfaces the data points that separate your group from the ones either side of it.

06 How much screen time is normal?

Common Sense Media's 2021 census put US teenagers at 8 hours 39 minutes of screen media a day, up from 7 hours 22 minutes in 2019, and tweens at 5 hours 33 minutes. No consensus safe threshold exists for adults. Self-reported screen time undercounts the measured figure by 20 to 40 percent in studies matching iOS Screen Time data against surveys, so nearly everyone is on their phone longer than they say. The hour after waking and the hour before sleep are the heaviest windows for adults and teens alike. The inner monologue tool and the snooze button calculator cover neighbouring daily habits.

07 How many countries has the average person visited?

Pew Research and YouGov surveys put the median American at around 3 to 5 international trips ever and roughly 12 to 15 countries visited, counting brief stops. UK medians run nearer 10 countries, a legacy of frictionless intra-EU travel. Globally the picture is different again: most people will never visit more than 3 countries in their lifetime. Thirty or more countries puts you in roughly the top 5 percent of any developed-country population, and 50 or more in the top 1 to 2 percent. Passport privilege does much of the work, since passports differ hugely in how many countries they open without a visa, as the Henley Passport Index shows. Travel also follows a J-curve with age: 25 to 34 year olds add countries fastest, the rate collapses under parenting demands, then climbs again from 55 onward as discretionary income returns. The countries visited calculator shows your travel percentile against the US and global distributions.

08 How many close friends should I have?

Robin Dunbar's work on stable social networks describes layers rather than a single number: roughly 5 people in the support clique, 15 in the sympathy group, 50 close associates and 150 stable acquaintances, that last figure being Dunbar's number. Population data lands close to it. The Survey Center on American Life puts the median US adult at 3 to 5 close friends, with about 12 percent reporting none at all, up from 3 percent in 1990. Loneliness is now handled as a public health matter, and the US Surgeon General's 2023 advisory tied chronic social isolation to a mortality risk comparable with smoking 15 cigarettes a day. Adults aged 18 to 34 report more loneliness than over-65s for the first time on record. Men report fewer close friends than women at every age above 30, and the gap widens after 50. A University of Kansas study puts the price of a new adult friendship at 90 to 200 hours of shared activity before it feels close. The friendship count calculator places your close-friend count against the population, and adult friendship statistics covers the trend in depth.
