America’s Birthday Patterns Reveal Demographics in New Chart
Have you ever noticed that certain months seem to have daily birthdays in your social circle? Kremp Florist’s new study shows birth patterns that reveal remarkable consistency in when people are born and interesting age variations across the states. Through analysis of data from 29.8 million births recorded from the CDC WONDER Natality database and nearly 16 million census survey responses, the data unveils hidden demographic patterns that shape everything from our family planning to regional economics.

The standout finding is in the most popular birth month. August is by far the most common birth month in 45 out of 50 states. This consistency reflects a few factors that we can tie to conception periods. Late fall to early winter is an ideal time to start a pregnancy. Counting nine months back from August indicates a conception period in November to December. Chill outdoor temperatures encourage more intimate indoor time, and festive dates like Thanksgiving, Christmas, and New Year’s provide opportunities for relaxation and celebration. The positive mood can foster romantic connections.
Science also supports this pattern, suggesting that sperm quality peaks during the winter months and declines in the summer heat since sperm prefer a cooler environment, and high temperatures reduce the quantity and mobility of sperm. Female fertility is affected by the seasons, too. Shorter fall and winter days boost melatonin production, which supports the circadian rhythms that stabilize fertility hormones like prolactin.
The data also goes so far as to reveal the most common single birthday in America. While August dominates the monthly birthday rate, the most common individual birthday is September 9th. There have been about 12,301 birthdays celebrated annually on that day for the past 20 years. This specific birthday is a shared experience for many people, including celebrities like Adam Sandler, Otis Redding, Michael Bublé, Hugh Grant, Leo Tolstoy, and Colonel Sanders.
The team’s analysis also shows us state-by-state age demographics that reflect economic opportunities, migration patterns, and other cultural factors. Maine is the oldest state in America, with a median age of 55. Populations there are living longer, and birth rates are on the decline. Utah has the youngest population, with an average age of 37. The youthful makeup of Utah stems from the state’s high birth rates and youthful urban population.
We generally see older populations in northeastern states like Vermont, New Hampshire, and Delaware. Western and mountain states skew younger, like in Idaho, Texas, and Colorado. These demographics are influenced by economic development, healthcare demands, educational opportunities, and other factors that influence migration to and from the state and longevity.
Kremp’s graphic shows some fascinating regional patterns and consistency trends in ages and birth timing. All these factors help shape America’s diverse landscape and unique regional identities.

Study Examines Where People Think AI Will Improve Their Work Lives
AI is embedded in workplaces worldwide by this point, and yet workers’ feelings about it vary dramatically. A study by Qualtrics examined how geography was related to feelings about AI in the workplace. They found that only 37% of workers globally believed that AI would improve their jobs. That average hides a 45-point difference between the most optimistic country, which is China, and the most skeptical, Japan.

Nearly 80% of global companies report using AI in some capacity, and research indicates productivity gains, with lower-skilled workers benefiting the most. Even if this is the case, employee sentiment isn’t nearly as unified. The numbers the team shows here indicate a healthy level of AI skepticism. In fact, more than half of workers think AI will improve their lives in just 6 out of 32 countries studied. That means there are more skeptics than people excited about what AI will bring to the workplace. But why does optimism cluster in some regions while most remain skeptical?
Here are a few of the countries where optimism runs high:
- China – 62% of workers are optimistic
- Indonesia – 59%
- Peru – 57%
- South Africa – 53%
- Thailand – 52%
There is a mid-tier region with fewer optimistic workers, but still a healthy percentage. This includes Mexico, Brazil, India, Colombia, and Malaysia. Many of these countries have developing economies or a heavy state investment in AI infrastructure, as is the case in China. Workers in these places view AI as a tool to close skill gaps, raise wages, and improve living standards. These regional differences are easy to spot thanks to the map Qualtrics created, which color codes the level of optimism/skepticism.
At the other end of the spectrum, we find the highest number of skeptics in Western Europe and English-speaking countries. Here are the countries with the least faith in AI:
- United States – 31% of workers are optimistic
- Australia – 29%
- Great Britain – 26%
- Canada – 24%
- Japan – 17%
- Poland – 21%
The media narratives in these countries frame AI as a risk of automation-driven job loss, which shapes people’s perceptions even when AI adoption in their workplaces is the same as in optimistic locations. These nations are the same that rank lowest on the belief that AI will improve the job market.
Economic research suggests that AI tends to reshuffle tasks within a role rather than eliminate that job outright. New skills will be required to work with AI, and some positions will shift, but historically, new digital tools have created more roles than they’ve erased. The gap between the hard data and public sentiment in skeptical countries is definitely worth examining and tells a story.
As AI rolls out unevenly across the world’s workforce, it’s important for employers to understand where their employees actually stand on the issue. Beyond regional stereotypes or headline-driven assumptions, employers must look at facts like the data presented here to make thoughtful AI adoption decisions.

The U.S. Cities Where Renting Means Bracing for a Move
Moving consistently ranks among life’s most stressful experiences, behind only divorce and the death of a loved one. This difficulty isn’t even distributed by location. Some cities make a renter’s move dramatically more difficult than others. Rove Lab’s analysis of 55 major U.S. metro areas, scored across 13 factors including population density, rental housing, transportation, and weather, shows which cities make moving a logistical nightmare.
Click below to zoom.
The New York-Newark-Jersey City metro area is the most difficult one to move from, with a score of 77.16. There are several reasons it’s so difficult. For one, it has the highest population density in the country, at 3,247.7 people per square mile. It also has the lowest renter turnover at 19.7%, indicating fierce competition for available units. 57.2% of rental properties are large buildings with more than 10 units, and the median building age is 65. This means these older buildings have narrow stairwells, slow elevators, and tight corners, a nightmare on moving day. On top of this, the transit density at peak hours is 212 vehicles per square mile. Trying to move out of an older building with narrow hallways, busy stairs and elevators, and limited street parking is truly challenging.
Move-in difficulty varies widely by city. Los Angeles isn’t the densest city, but it has the worst traffic congestion in the country, with 7 hours and 49 minutes of traffic per weekday, due to urban sprawl and car dependence in the region. Washington, D.C. has the oldest housing units, making it more challenging to navigate furniture on move-in day, especially in dense transit corridors. San Francisco and Chicago are mid-density metros with older buildings and a high number of large buildings with many units, driving up the scores. Boston and Seattle round out the top of the most difficult cities, thanks to lots of snow in Boston and tons of rainy days in Seattle, which make moving in more difficult.
Thankfully, the team’s data also shows that not every city is a move-in nightmare. Austin is a standout city with the highest renter turnover in the country. A pandemic-era construction boom created an oversupply of new, modern housing units, which led landlords to offer move-in incentives and upgrades. Fresno, Riverside-San Bernardino, and Birmingham all offer easier moves thanks to a low population density, newer rental stock, and less traffic. The weather’s role shouldn’t be overlooked. Rochester, Buffalo, and Pittsburgh all have lots of snowy and rainy days, which can really put a literal and figurative damper on moving day.
The Rove Lab team’s work reframes the question of which cities are best and worst to live in through a specific, practical lens. Your housing is one of the most important parts of your life in a new city, and finding the best rental and having a good move-in experience will set the tone for a new start. Wherever you’re headed, knowing what you’re walking into can help you have the best experience.

Report Examines Languages on the Way to Extinction
When a language disappears, a worldview, history, and culture fade with it. There are thousands of languages at risk of going extinct, as a report from Preply shows. Their Endangered Languages Report gathers data showing where the crises are most acute, while offering hope that extinction isn’t inevitable. They’ve shown areas where revival is working, too. The study highlighted problem areas in vanishing languages, the reasons they are in danger, and hopeful signs that languages can be revived.

Australia leads the world in the number of critically endangered languages indigenous to its borders (133). In general, the Pacific region and islands have the most endangered languages overall, at 250. Africa has the highest number of threatened languages at 217. In many of these locations, globalization puts pressure on Indigenous and isolated communities. A globalized world pushes young working-age people toward learning a globally dominant language like English or Mandarin, so they have expanded opportunities. It’s worth paying attention to the scale the study creates with at-risk, vulnerable, threatened, endangered, severely endangered, and critically endangered languages. This shows that risk is a spectrum in the world of language, just as it is in plant and animal species.
In the data, a language stands out as a relative success story. Welsh is a vulnerable language, with 19%–20% of the population speaking it. After over 50 years of effort and education, it rose to 30% of children between 3 and 15 years old who spoke it. The nation of Wales set a goal of a million fluent speakers by 2050. If they can meet that goal, it will prove that policy and education can revive a language.
The Lakota language is a cautionary tale of historical oppression. There are only 2,000 speakers today and it’s an endangered language. The United States assimilation policies pushed Indigenous people into residential schools, where children were forced to drop their language and speak English. Today, only 1% of the Lakota population of 170,000 can speak their native language fluently.
Cornish is a rare and unique language brought back from extinction. It officially went extinct in the 1800s, and thanks to a standardized written form revived and adopted in 2008, there are now 557 speakers of a once-dead language.
“Awakening” languages are revivals of once-extinct languages, like Cornish. Kaurna, an Australian language, was nearly lost when the last speaker passed away in 1929. But a program worked to revive it among 50 speakers using dictionaries, songs, and formal education programs. These aren’t the only awakening languages. Wampanoag, Palawa Kani, and Natchez have also awakened back into existence. Revitalization is slow, meticulous work, but these languages show that it’s possible.
Non-native speakers can do their part to support efforts by studying an at-risk language or helping out a revival group. Native speakers carry the heaviest burden and will most effectively save a language by teaching it to their children early. Schools and governments also have a part to play by offering classes in endangered languages. Language survival is possible when ordinary people decide the language is worth speaking.
