Working from home in the United States has become a new standard beyond a temporary work arrangement. Positive changes such as reduced commuting time, expanded employment and a higher birth rate have emerged, while worries are also growing over a weakening downtown economy and AI replacing jobs.

Business Insider reported on Oct. 14 that the share of work-from-home days in total U.S. workdays has held at about 26 percent over the past two years. That is below 62 percent at the start of the pandemic but about four times the 7 percent level in 2019.

Nick Bloom (닉 블룸), a Stanford University economist, pointed to time savings as the biggest effect of working from home. U.S. workers save an average of 1 hour and 30 minutes per day when working from home. Workers in technology and finance save about 3 hours a week. The time saved was used for sleep, exercise, cooking and childcare.

The job market has also changed. As remote and hybrid work spread, the number of disabled full-time employees increased by more than 250,000, and it helped women with heavy childcare burdens stay employed. Bloom estimated that "hybrid work could raise the labor force participation rate and gross domestic product (GDP) by 1 to 2 percent each".

Positive links were also found in birth and environmental indicators. Researchers said working from home in the United States and Northern Europe is associated with a birth rate about 5 percent higher. Nitrogen dioxide concentrations in the centers of major U.S. cities were 8 percent lower in 2025 than in 2019. The annual reduction in deaths from improved air quality was estimated at 1,500 to 3,500 people.

Downtown economies, however, took a hit. San Francisco's second-quarter office vacancy rate reached 29 percent. The share of operating costs covered by fare and parking revenue at the Bay Area Rapid Transit system fell to 23 percent from 70 percent in the past.

Working from home also accelerated the spread of AI. Workplace conversations have accumulated as digital records on messengers and video meetings, expanding the basis for using AI. Bloom warned that "fully remote office work may be relatively vulnerable to automation".

Working from home has raised productivity and quality of life while becoming a key factor reshaping urban economies and employment structures.
