Map of people moving during pandemic

It was only a matter of time before someone showed dots moving across a map to show migration during the pandemic. Again, using USPS change of address data, Yan Wu and Luis Melgar for the Wall Street Journal (paywalled) showed where people moved in the country. As shown through other views, a lot of the movement wasn’t out of the ordinary, but in some areas — mainly San Francisco and...

Where people moved during the pandemic

In another look at migration through the lens of USPS change of address data, Bloomberg CityLab shows where people moved during the pandemic, focusing on movement in and out of metro areas. With the exception of San Francisco and New York, most areas didn’t see much movement distance-wise: Even in the biggest metro areas, most people didn’t go very far. In the country’s 50 most populous cities, 84% of the...

Maps of migration to smaller cities

Steven Bernard for Financial Times, in a report by Claire Bushey and Steff Chavez, mapped net inflows (paywalled), based on property searches on home listing site Redfin. This shows a slightly different angle from NYT’s analysis, which showed less change year-over-year. Tags: Financial Times, housing, migration

Pandemic migrations

With the restrictions of the pandemic, you might expect an unusually big wave of people leaving cities for more open space. Using USPS’s change of address data, Jed Kolko, Emily Badger and Quoctrung Bui, for NYT’s The Upshot, show that this was not quite the case. This surprised me, because I live in a suburban area that saw a flux of home buyers, which made prices approach ridiculous ranges. I...

Bird migration forecast maps

BirdCast, from Colorado State University and the Cornell Lab of Ornithology, shows current forecasts for where birds are headed over the United States: Bird migration forecasts show predicted nocturnal migration 3 hours after local sunset and are updated every 6 hours. These forecasts come from models trained on the last 23 years of bird movements in the atmosphere as detected by the US NEXRAD weather surveillance radar network. In these...

Deer crossing across highway corridors

With the climate changing, animals will need to migrate to different areas to live, but that can be a challenge when there is a giant highway blocking the way. The Washington Post looks at how scientists in Wyoming are hoping to clear the path: “We can’t predict exactly what the impacts of climate change are going to be, or what species are going to be impacted,” said Hall Sawyer, a...

Traveling birds on a thousand-mile journey

Birds migrate to areas more hospitable, but where do they go? It depends on the bird. It depends on the time of year. It depends on other various factors. Drawing from several data sources, National Geographic maps how birds migrate thousands of miles. View it on your desktop of maximum animated pleasure. Tags: birds, migration

Visual narrative of six asylum seekers

We often visualize migration and people movement as lines that go from point A to point B. While this can be interesting for overall trends, we lose something about the individuals leaving their home and traveling in hopes to find something some better. Federica Fragapane, in collaboration with Alex Piacentini, focuses in on six people leaving point A for point B to tell their stories. Tags: asylum, migration

Animal migrations in animated map

The Migrations in Motion map, by Dan Majka from the The Nature Conservancy, shows modeled animal migrations in North and South America. Researchers from University of Washington and The Nature Conservancy modeled potential habitat for 2954 species using climate change projections and the climatic needs of each species. Using flow models from electronic circuit theory, they plotted movement routes for each species, connecting current habitats with their projected locations under...

Refugee migration mapped globally

According to estimates recently released by the United Nations, about 14 million left their home countries because of conflict or persecution. Sergio Pecanha and Tim Wallace for the New York Times mapped the migrations. After the data, there are two things that make this series of maps. The first is the projection, azimuthal equidistant, centered on areas where there is the most activity. The second is the use of line...
