Black neighborhoods split by highways

Rachael Dottle, Laura Bliss and Pablo Robles for Bloomberg on how urban highways often split communities:

By the 1960s, the neighborhood’s business core was gone, replaced by newly constructed Interstate 94. Homes that had been a short walk to the shops now overlooked a six-lane highway shuttling commuters between the Twin Cities of Minneapolis and St. Paul. Homes and businesses were seized and destroyed under eminent domain. The neighborhood was split in two.

Atlas of the Invisible

James Cheshire and Oliver Uberti teamed up for another book of maps, Atlas of the Invisible:

Sometimes we miss what we can’t step back to see. Sometimes the invisible only appears with the creep of time. And sometimes, in the case of historical events, the visible becomes invisible with the loss of a generation. Graphics give us the power to zoom out, to compare, to remember.

This is their third book together, the first two being London: The Information Capital and Where the Animals Go. Atlas of the Invisible is available in the UK and available for pre-order in the US. It looks promising.

New Orleans power outage seen via satellite imagery

After Hurricane Ida, New Orleans experienced power outages. The NASA Earth Observatory show the outages by comparing night lights on August 31, 2021 against night lights on August 9, 2021:

VIIRS has a low-light sensor—the day/night band—that measures light emissions and reflections. This capability has made it possible to distinguish the intensity, types, and sources of lights and to observe how they change. The data are then processed by the Black Marble team to account for changes in the landscape (such as flooding), the atmosphere, and the Moon phase, and to filter out stray light from sources that are not electric lights.

Tracking wildfires in the west

Wildfires continue to burn in the western United States. The New York Times provides a tracker showing the ones burning now, along with air quality and a smoke forecast.

A couple of weeks ago, it smelled of smoke in my area and the sky was orange. I guess this is the new norm.

Diversity within the Asian population

Robert Gebeloff, Denise Lu and Miriam Jordan for The New York Times looked at overall increases and variation within the Asian population:

North Dakota, South Dakota, Texas, North Carolina and Indiana are among states that experienced major growth in the past decade. And people of Asian descent have been settling in ever larger numbers in states like West Virginia, where the overall population has declined.

Race and ethnicity map of dots

CNN goes with the dot density map for their first pass on the 2020 decennial. Each dot represents a certain number of people depending on your zoom level. Color represents race or ethnicity.

Does CNN have a limited color palette that they’re allowed to use? I would’ve gone for more contrast between the light blue for white and darker-but-still-light blue for American Indian/Alaskan Native.

See also: Dustin Cable’s racial dot map from 2013 and Erica Fischer’s dot maps of the same flavor from 2010.

Shift in white population vs. people of color

The New York Times go with the angled arrows to show the shifts in racial population. The red-orange arrows show an increase in the share of white population, and the teal arrows show an increase in the share of people of color. Longer arrows mean a greater percentage point change.

Whereas The Washington Post focused more on the changes for each demographic individually, NYT focused more on how two broad groups compared.

Maps of racial population change

Using their peaks and valleys metaphor, The Washington Post shows the shift in racial population between 2010 and 2020. The open triangles, one for each county, show population with width, population growth with height, and fastest-growing race or ethnicity with color.

You might recognize the form from the Post’s 2016 election results, but there’s a small wrinkle when you look at the breakdowns for individual groups. The triangles flip upside down for where population decreased.

Where America is expanding in developed areas

Zach Levitt and Jess Eng for The Washington Post mapped newly developed areas in the contiguous United States, between 2001 and 2019:

Between 2001 and 2019, the built-up landscape of America — buildings, roads and other structures — has expanded into previously undeveloped areas, adding more than 14,000 square miles of new development across the contiguous United States — an area over five times the size of Delaware.

My favorite part is the interactive map, which lets you see development in your area. The purple indicating newly developed areas against the grayscale provides a quick reference.

The maps are based on data from the United States Geological Survey, which you can grab here.
