Vital Signs
Vital Signs is MTC’s interactive website that tracks data and trends in the Bay Area — to help plan for the future.
MTC is monitoring the Bay Area’s performance on a range of measures to better understand where the region is succeeding, and where it is falling short.
The Vital Signs website helps MTC and partner agencies make better decisions about transportation, land use, the environment and the economy.
Visit the Vital Signs website to find regional progress on topics such as average commute time or median home price. Check out the data visualization tools and download raw data sets.

MTC invites you to discover:
- Which freeway is the most congested?
- How many more people ride BART than AC Transit?
- Are potholes worse in my neighborhood than in other communities?
- Which cities and towns are permitting the most housing?
- How does housing affordability compare throughout the region?
- Which neighborhoods are hotspots for displacement risk?
- Has the air become cleaner over time?
- How does the Bay Area compare to other major metro areas?
