Census Bureau data collected earlier this year has shown that natural disasters forced an estimated 3.4 million people in the U.S. to leave their homes in 2022, underscoring how climate-related weather events are already changing American communities.
According to reports, the overwhelming majority of these people were uprooted by hurricanes, followed by floods, then fires and tornados. While nearly 40% returned to their homes within a week, about 16% have not returned home (and may never do so) and 12% were evacuated for more than six months.
The Census Bureau count is based on 68,504 responses it received as part of the Household Pulse Survey conducted Jan. 4-Jan. 16. The data collection is known to be one of the few federal efforts to track displaced people, starting only in 2020. The bureau does note that the data is โexperimental,โ and is extrapolated based on its sample data.
โThese numbers are very distressing,โ said Michael Gerrard, director of the Sabin Center for Climate Change Law at Columbia University, who was not involved in the data collection. โThese numbers are what one would expect to find in a developing country. Itโs appalling to see them in the United States. โฆ Theyโre only going to get worse in the years to come because climate change is making extreme weather events more frequent and more severe.โ

The data showed that some states experienced far more of an impact than others. For instance, Florida had more than 888,000 people displaced whileLouisiana had more than 368,000 displaced.
The U.S. was hit by a series of major disasters in 2022. The National Oceanic and Atmospheric Administration said that 18 extreme weather events had each caused at least $1 billion in damage. Climate experts have warned for years to expect more intense weather disasters as global temperatures rise.
Recall that data from the Internal Displacement Monitoring Center previously estimated that disasters displaced an average of 800,000 U.S. residents a year from 2008 through 2021.
โThe United States is not in the least prepared for this,โ Garrard said. โOur settlement patterns have not reflected the emerging risks of climate change to the habitability of some parts of the country.โ
The data showed that the more than half a million people who never returned home experienced multiple hardships, including lack of housing, food, water, sanitation and child care.
โThese are all things that we take for granted in a modern society,โ Gerrard added. โIts absence is deeply disruptive to physical and emotional health as well as to child development.โ
The data further showed differences between people of different economic statuses, races and identities. It showed that those earning less than $25,000 a year had the highest evacuation rate of any economic group while Black and Hispanic residents had slightly higher evacuation rates than white residents.
