Searching for the densest square kilometer in different cities

Based on data from Gridded Population of the World, geographer Garrett Dash Nelson calculated the square kilometers in major cities with the highest population density. On CityLab: In the interactive visualization, I’ve taken GPW data for a curated selection of American cities. Some have old, historic cores, and others are dominated by more recent development; some have constricting physical geographies and others lie on relatively flat, open plains; some were...

Population mountains

You’ve seen the maps of population density. You’ve seen the jokes. But you haven’t seen population at high granularity in a 3-D view. Matt Daniels for The Pudding used a mountain metaphor to show the peaks and valleys of population around the world. You get more out of the data in this view than you would the overhead, which tends to obscure the variation in large cities. Although if you...

World population estimator and gridded data from NASA

Population data typically comes in the context of boundaries. City data. County data. Country data. With their Population Estimate Service, NASA provides data at higher granularity. You can request estimated population in the context of a world grid. Here’s an interactive map to demonstrate the API. Click and drag a shape across any region in the world and get an estimate of the population within that shape. [via kottke] Tags:...

Common Ground Between North and South Korea: Aging and Shrinking Populations

The birth rate in South Korea, where I live and work, hit a record low this year, leading to concern about the impact an aging (and, eventually, shrinking) population might have on the nation’s society and economy. These charts show the long-term trends, both in actual population and projected changes, according to United Nations data. I’ve added North Korea, which actually has a higher fertility rate today, for context. First,...

Mapping South Korea’s Total and Foreign Populations — by Municipal District

South Korea, my adopted home for almost two years, has about 50 million residents as of the last census, in 2015. Most of them are settled in the country’s urban areas. About 22 million residents, for example, live in Seoul, the capital in the country’s northwest corner, and its adjacent province, Gyeonggi. As an experiment to create a choropleth map with D3 and NPR’s dailygraphics rig, which drives most of...

Majority minorities

We saw the changing percentage of white people in the United States and how whites are not the majority in a lot of places. Who is the majority in these areas? Here’s a breakdown for the main three races that make up majorities. Black: Hispanic: Native American: Tags: animation, population, R, race

Percentage of white people

Below is the estimated percentage of white population in the United States from 1970 to 2010, based on data from the Census Bureau and made more accessible by NHGIS. I like the evaporative quality coming up in the southwest. Mostly though, this is just me trying out a new toy, and the form fascinates me at the moment. Members: I’m working on a set of tutorials for how to make...
