How much does NIH spend on medical research each year?

The interactive chart needs JavaScript. The numbers are on the chart's page.

NIH funded $42.2 billion of research projects in fiscal 2025, up from $27.8 billion in 2012, before adjusting for inflation. The most in a year was $43.6 billion, in fiscal 2023; the dip in 2013 was the federal budget cut known as sequestration. These are the projects NIH lists in RePORTER, grants and its own labs; NIH's full budget, which also pays for buildings and running the agency, is larger.

Which big U.S. cities have the highest murder rates?

The interactive chart needs JavaScript. The numbers are on the chart's page.

In 2025 St. Louis, MO had the highest murder rate of the 89 biggest U.S. cities whose police reported a full year to the FBI, about 51.3 per 100,000 people, followed by Memphis, TN (31.0) and Cleveland, OH (28.0). Irvine, CA (0.0) and Plano, TX (0.7) had the lowest; the U.S. rate was about 4.4. Departments that didn't report a full year are left out (for 2025, New Orleans, Orlando and St. Petersburg, Florida). Each rate is per person the department serves, and a few, such as Las Vegas, Honolulu, Jacksonville and Louisville, serve their whole county. A city's rate also depends on where its borders fall, so compare cities with care.

How to read this chart

Each bar is the number of murders in a city in one year for every 100,000 people its police department serves. The dashed line is the U.S. rate. Murders are rare, so in a smaller city a handful more or fewer in one year can move its rate and its rank a lot.

Questions to discuss

  1. How many cities on the chart have a murder rate above the U.S. rate, and how many are below it?
  2. Why does a chart like this use murders per 100,000 people instead of the total number of murders in each city?
  3. A city's rank can jump from one year to the next. Why might small numbers make rates bounce around?
