The Population Density of Europe (and the World) in Two 3-D Maps
How many people live in Europe? The population of Europe is around 745 million people, or 10% of the world population. Internationally recognized data analyst, mapmaker, author, and visual storyteller Alasdair Rae has transformed this figure into a captivating population density map of the entire continent! Check it out:

Rae states: “The maps below use 1km x 1km data and the height of the bars represents the number of people living in any one square. The big squares are 50km x 50km (about 30 miles) and are there to provide sense of scale. The highest 1km densities are found in Spain and France, and Madrid, Barcelona and Paris in particular where you get values of more than 50,000.” You can explore more detailed sections of Europe here, as well as the creator’s insights and methods. You can also other fascinating data visualizations, such as the most densely population square kilometer in every U.S. state!
This got me thinking – what would an entire world map made like this look like? He actually made a complete map too! I wanted to provide both maps to provide a more “big picture” understanding of scale.

As you can see, in the grand scheme of the whole planet, Europe’s population density seems so humble. So what are the most densely populated cities in the world based on people per square kilometer? Try to take a guess based off of this map (test your geography knowledge!) and then check the list:
- Manila, Philippines (Asia) – 43,062
- Mandaluyong, Philippines (Asia) – 38,495
- Pateros, Philippines (Asia) – 37,061
- Caloocan, Philippines (Asia) – 31,233
- Bnei Brak, Israel (Asia) – 30,001
- Kathmandu, Nepal (Asia) – 29,161
- Dkaka, Bangladesh (Asia) – 29,069
- Makati, Philippines (Asia) – 28,975
- Port-au-Prince, Haiti (North America) – 27,395
- Levallois-Perret, France (Europe) – 26,713
The European city with the highest population density is Levallois-Perret in France, but it is nearly 20,000 people per square kilometer less than Manila, the most densely populated city in the world. While Americans in New York City or Los Angeles may fret over crowds and traffic, the truth is, none of America’s cities even rank in the top 50 for population density.

Map Reveals the Loudest and Quietest Places to Sleep in the U.S.
Noise pollution can have a major impact on sleep quality, and NapLab’s latest study sheds light on the noisiest and quietest places to get a good night’s rest in the U.S. Using data from the National Transportation Noise Exposure Map, they pinpointed areas with the highest and lowest decibel levels.

The three loudest cities were all in Colorado: Denver, Aurora, and Colorado Springs. These cities experience a mix of factors contributing to the noise, including rapid population growth, which increases traffic and construction noise. Denver International Airport, one of the busiest airports in the country, adds constant aviation sounds to Denver and Aurora. Meanwhile, Colorado Springs is home to several military bases, where aircraft activity and training exercises raise noise levels even further.
On the other hand, the quietest places for sleep were found in Zephyrhills, Florida, Cape Coral, Florida, and Lakewood Township, New Jersey. These locations benefit from a slower pace of life, less urban development, and fewer transportation hubs. Zephyrhills and Cape Coral are popular with retirees and seasonal residents, leading to quieter neighborhoods. Cape Coral also enforces strict noise ordinances to maintain a peaceful environment. Lakewood Township offers an outdoor-focused, laid-back lifestyle with activities like golfing and canoeing that contribute to its calm atmosphere.
Whether you’re seeking tranquility or braving city sounds, this map offers insight into how your environment might affect your sleep.

Study Reveals the Most Sexually Adventurous States in America
Ever wondered which states are the most daring behind closed doors? A recent Too Timid survey of 1,427 Americans sheds light on the most sexually adventurous states in the U.S. The study ranked states based on four key factors: the average number of sex toys owned, sexual partners, sexual experiences, and fantasies that turn people on.

Here are the top 10 most adventurous states:
- Montana
- Iowa
- Oklahoma
- Arkansas
- Minnesota
- New Jersey
- Oregon
- Nevada
- Alaska
- Indiana
Meanwhile, the least adventurous states include Rhode Island, North Dakota, Maine, and South Dakota.
Beyond state rankings, the study uncovered some intriguing trends in American bedrooms. The most common sexual experience is watching porn with a partner, followed by one-night stands. When it comes to fantasies, most people keep it simple, dreaming about sex with their current partner and enjoying some steamy dirty talk.
The Too Timid team highlights the positive effects of sexual openness, noting that people who embrace their sexuality often report better body image, stronger relationships, and more satisfying sex lives.
While this survey offers a fascinating glimpse into America’s intimate habits, more data and future studies could reveal even more surprising trends. Whether your state made the top ten or not, one thing’s clear—America’s curiosity about sex is alive and well!

Study Highlights Disparity Between Homelessness Rates and Empty Housing
Homelessness in the United States remains a pressing issue, especially as rates have surged by 18.1% in 2024—a historic high. Vulnerable populations face rising housing costs, mass migration, and evictions, with many renters categorized as “cost-burdened.” Meanwhile, over 14 million vacant homes exist across the country, a number that far exceeds what’s needed to house every homeless individual.
A study by the Mortgage Calculator team maps this disparity, highlighting states with the highest ratio of vacant homes to homeless individuals. Mississippi tops the list with 187.31 vacant homes per homeless person. Despite high poverty levels, the state’s low cost of living and relatively small homeless population contribute to this striking ratio. Southern states dominate the map’s highest ratios, reflecting the availability of vacant housing in rural areas. However, these areas often lack the economic infrastructure and job opportunities necessary to support new residents, complicating potential solutions.
The findings reveal stark contrasts: urban areas, where jobs are more plentiful, tend to have higher homelessness rates but fewer vacant homes, while rural states have the opposite challenge. Advocates suggest that leveraging vacant housing could significantly reduce homelessness, but practical barriers remain. Addressing this issue will require not only repurposing unused housing but also creating sustainable economic opportunities to support vulnerable populations.
This study underscores the urgent need for innovative policies and programs to bridge the gap between empty housing and homelessness, offering hope for a more equitable future.
