Visualizing Over A Century of World Fertility

In just 50 years, world fertility rates have been cut in half.

This sea change can be attributed to multiple factors, ranging from medical advances to greater gender equity. But generally speaking, as more women gain an education and enter the workforce, they’re delaying motherhood and often having fewer children in the process.

Today’s interactive data visualization was put together by Bo McCready, the Director of Analytics at KIPP Texas. Using numbers from Our World in Data, it depicts the changes in the world’s fertility rate—the average number of children per woman—spanning from the beginning of the 20th century to present day.

A Demographic Decline

The global fertility rate fell from 5.25 children per woman in 1900, to 2.44 children per woman in 2018. The steepest drop in this shift happened in a single decade, from 1970 to 1980.

In the interactive graphic, you’ll see graphs for 200 different countries and political entities showing their total fertility rate (FTR) over time. Here’s a quick summary of the countries with the highest and lowest FTRs, as of 2017:

Top 10 CountriesFertility rateBottom 10 CountriesFertility Rate
🇳🇪 Niger7.13🇹🇼 Taiwan1.22
🇸🇴 Somalia6.08🇲🇩 Moldova1.23
🇨🇩 Democratic Republic of Congo5.92🇵🇹 Portugal1.24

🇹🇩 Chad5.75🇵🇱 Poland1.29
🇦🇴 Angola5.55🇬🇷 Greece1.3
🇧🇮 Burundi5.53🇰🇷 South Korea1.33
🇺🇬 Uganda5.41🇭🇰 Hong Kong1.34
🇳🇬 Nigeria5.39🇨🇾 Cyprus1.34
🇬🇲 Gambia5.29🇲🇴 Macao1.36

At a glance, the countries with the highest fertility are all located in Africa, while several Asian countries end up in the lowest fertility list.

The notable decade of decline in average global fertility can be partially traced back to the actions of the demographic giants China and India. In the 1970s, China’s controversial “one child only” policy and India’s state-led sterilization campaigns caused sharp declines in births for both countries. Though they hold over a quarter of the world’s population today, the effects of these government decisions are still being felt.

Population Plateau, or Cliff?

The overall decline in fertility rates isn’t expected to end anytime soon, and it’s even expected to fall past 2.1 children per woman, which is known as the “replacement rate”. Any fertility below this rate signals fewer new babies than parents, leading to an eventual population decline.

Experts predict that world fertility will further drop from 2.5 to 1.9 children per woman by 2100. This means that global population growth will slow down or possibly even go negative.

Africa will continue to be the only region with significant growth—consistent with the generous fertility rates of Nigeria, the DRC, and Angola. In fact, the continent is expected to house 13 of the world’s largest megacities, as its population expands from 1.3 billion to 4.3 billion by 2100.

Visualizing the Footprint of Highways in American Cities

Highways improved mobility for the average American, ingraining the automobile into the urban fabric of American cities, for better and worse.

The Impact of Highways

Footprint of Highways in American Cities

Visualizing the Footprint of Highways in American Cities

Driving on the open road is a defining feature of the American experience, made possible by coast-to-coast highways. It defined a generation of life and ingrained the automobile into the urban fabric of American cities, for better and worse.

Today’s animations show how highways reshaped the downtown cores of six American cities and created new patterns of urban life. But first, some background information on the creation of the interstate system.

The Interstate Highway System

The U.S. Interstate System was created on June 29, 1956, when Dwight Eisenhower signed the Federal-Aid Highway Act. It would eventually run 46,876 miles, cost $521 billion and take 36 years to complete.

Map of the US Interstate System

From San Diego to Bangor, the interstate highway system connected Americans and opened up the country to commerce and geographic mobility like never before, but for all its benefits, this new transportation network ripped through established patterns of urban and town life, creating a new era of urban development.

The Legacy of Highways: The Suburbs and Inner Cities

The vast geography of continental America helped to entrench personal mobility and freedom into American society. Highways and automobiles accelerated this lifestyle and even changed the shape of entire cities.

According to Prof. Nathaniel Baum-Snow of the University of Toronto, between 1950 and 1990, the population of central cities in the U.S. declined by 17% despite a population growth of 72% in larger metropolitan areas during the same period. Baum-Snow posits that, had the interstate highway system not been built, central cities’ populations would have increased 8%.

Firms followed the workers to the suburbs, but the highways system also created additional benefits for these firms. Cross-country road access freed manufacturing from ports and downtown rail hubs, while allowing economies to operate across larger distances, altering the dynamics of typical urban economies.

Faced with this new reality, inner cities struggled in years to come.

Inner Cities

The introduction of highways created an increase in the supply of land for development through faster commutes to outlying areas. In 1950, half of all jobs were located in central cities. By 1990, less than one-third of urban jobs were located in the core of American cities.

“Not TV or illegal drugs but the automobile has been the chief destroyer of American communities.” Jane Jacobs, Author The Death and Life of Great American Cities

Benefits of new development accrued to the outer areas while the construction of the highways in inner cities displaced largely low-income communities, segregated neighborhoods, increased the amount of air and noise pollution, devalued surrounding properties, and removed access to jobs for those without a car, further concentrating poverty.

Before and After: Six American Cities

A bird’s eye view of six American cities reveals what was and what is now. By overlaying existing highways over the neighborhoods they replaced, it becomes clear how much interstate construction drastically altered America’s urban landscape.

Oakland
Public opposition to the construction of I-980 was so strong that developers abandoned the project in 1971, only to complete it over a decade later.

Miami Highway
The I-95 carved through Miami’s largely black Overtown neighborhood. The construction of a single highway cloverleaf resulted in 20 square blocks being demolished, displacing over 10,000 people in that community.

Providence Highway
The I-95 comprised unconnected segments between 1957 and 1965 through the densest urban areas in a deliberate effort to prevent premature suburbanization and to revitalize the downtown core.

Cincinnati Highway
The I-71 cuts downtown Cincinnati off from its waterfront and a massive freeway interchange forced the destruction of dozens of blocks west of downtown.

Detroit highway construction
Freeway construction transformed Detroit between 1951 and 2010. Previously, its downtown had been surrounded by a high-density street grid. Today, it’s totally encircled by freeways.

Rochester Highway
Rochester is one of many cities opting to undertake freeway removal projects.

As the dotted line above shows, the “moat” surrounding downtown is slowly being removed. The city used reclaimed land from the Inner Loop freeway to construct three mixed-use developments that include below-market-rate units.

The Future of Urban Living: Do Highways Matter?

A new era of living is reconsidering the impacts of these highways on urban centers. As property values rise and existing housing stock is pressured, there are growing concerns over the environmental impacts of suburban life. As a result, urban planners and residents are looking to revitalize city cores and re-purpose land occupied by burdensome slabs of highway concrete.

Since 1987, there have been more than 20 urban highway segments removed from downtown cores, neighborhoods and waterfronts, mostly in North America. The pace of removals has picked up significantly and an additional 10 highways are now planned for removal in the United States.

During the COVID-19 pandemic, American cities have seen their traffic plummet. Rush-hour trips into cities are taking nearly half the time while some are not even commuting at all.

While this situation is likely temporary, it is offering a moment for reflection of how cities operate and whether the car should be at the center of urban planning.

At Risk: The Geography of America’s Senior Population

The U.S. senior population is much more vulnerable to COVID-19. Which states and cities have the most people in this at-risk age group?

U.S. Senior Population

At Risk: The U.S. Senior Population

The U.S. now has the largest number of confirmed COVID-19 cases globally, and modelling predicts that the country could see about 100,000 to 200,000 total deaths. Unfortunately, adults aged 65 or older—about 16% of the U.S. population—are at much higher risk of both severe illness and death.

Today’s chart uses U.S. Census Bureau data to map the percentage of the population that is 65 years or older by state. It also outlines the urban areas that are most heavily skewed towards this older age group.

Proportion of Seniors by State

Below is the full breakdown of the U.S. senior population by state, using the latest available data from 2018.

Maine tops the list with 20.6% of its population comprising adults age 65 or older. At the other end of the scale, Utah’s seniors make up only 11.1% of its population.

Notably, Florida has the second highest percentage and number of seniors nationwide. Its governor just announced the state’s stay-at-home order on April 1st, after taking criticism for refusing to do so earlier.

New York, the current global hot spot of COVID-19, is close to the national average with 16.4% of its population aged 65 or older. However, with over 3.2 million seniors, the sheer volume of individuals needing hospitalization has already put a strain on the state’s healthcare system. Governor Andrew Cuomo says the state will run out of its current supply of ventilators in less than a week.

The Most Vulnerable Urban Areas

*Urban areas consist of a downtown core and adjacent territories

With 6 areas in the top 10, Florida is quite vulnerable at the local level as well. Other states with multiple areas on the list include Ohio, Pennsylvania, and New York.

The Senior Population of Current U.S. Hotspots

To determine the vulnerability of current COVID-19 hotspots, we compared U.S. counties with a high number of cases per capita against their percentage of seniors.

Counties at the bottom left have low readings on both metrics. Conversely, counties in the top right have a dangerous combination: a high concentration of cases and vulnerable seniors.

senior population vs covid-19 outbreak

Multiple counties in New York occupy the top right quadrant, with Yonkers being the worst off. Los Angeles county, which has a similar population to all counties in New York City, has fewer cases and a smaller proportion of seniors.

To date, outbreaks have been mostly focused in urban areas where populations tend to be younger. However, as COVID-19 begins infiltrating rural areas, healthcare systems will need to contend with both older age groups and fewer resources.
