Power outages are a big problem in some of America's largest cities.
One in four households had a power outage within the 12 months before they were interviewed between May and September in 2023 by the federal government's American Housing Survey, which surveys the nation every two years.
And 70% of those households said the outage lasted 6 or more hours.
Homeowners experienced power outages more than renters: Around 28% of homeowners had an outage compared to 20% of renters.
Outages were also more common in rural areas, with around 35% of households reporting an outage in rual areas versus 23% in urban areas.
Still, among the 20 of the nation's biggest metros surveyed, an average of more than one in four of households reported a power outage.
The worst city for power outages was Cincinnati (46%), followed by Detroit (45%) and Cleveland (44%).
On the other hand, the best city for power outages was Miami (6%), followed by New York (11%) and Chicago (15%).
The ranking suggests that cities with more outages have poorer or aging grid infrastructure.
For instance, the second-worst city Detroit is in the state of Michigan which has one of the least reliable power grids.
But severe weather and electrical overloads during high heat are also big reasons some cities have it worse.
And Americans say the outages can cause mild to serious problems.
The most common difficulty households reported from outages was food spoiling (5%), having to stay somewhere overnight (3%) and missing work (2%).
But less than 1% of households reported that pipes froze, medicine spoiled or water collected in their basement or crawl space.
The outages also present unique difficulties for people with disabilities and their caregivers: Around 28% of households with at least one disabled person living there reported a power outage.
