Which states have the highest reported rape rates?

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

In 2025 Alaska had the highest rate of rapes reported to police, about 122 per 100,000 people, followed by Arkansas (72) and Montana (64). Connecticut (16), New Jersey (17) and Delaware (19) had the lowest; the U.S. rate was about 37. Many rapes are never reported, so these rates show reports, not how often rape happens, and they use the FBI's broader definition adopted in 2013. Rates count only the police agencies that reported to the FBI; in a few states, such as Florida and Mississippi, those cover only about 80 to 85% of residents. Since 2021, when the FBI began taking only its newer NIBRS reports, state rates don't line up exactly with earlier years.

Questions to discuss

  1. In one sentence of your own, what does this chart show?
  2. Find the biggest change or difference in the chart. What might explain it?
  3. Who collected these numbers, and how recent are they? What else would you want to know before drawing a conclusion?

Chart 2 of 2 · Energy

Where does US electricity come from?

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

In 2025 natural gas made 40.8% of US electricity, followed by nuclear (17.7%) and coal (16.6%). Wind made 10.5% and solar 6.7%. Solar counts only utility-scale plants, not rooftop panels, and the 2025 figures are preliminary.

How to read this chart

Each bar is one energy source's share of all the electricity made in the U.S. in a year, so the bars add up to about 100%. The bars start at zero, so a bar twice as long means twice the share. Solar counts only large power plants, not panels on rooftops.

Questions to discuss

  1. Which source makes the most electricity? About how many times more than the smallest bar?
  2. Which of these sources burn fuel and which don't? What share of electricity comes from each group?
  3. Why might a chart of this kind look different in your state than for the whole country?
