How much does a dozen eggs cost in the US?
The interactive chart needs JavaScript. The numbers are on the chart's page.
A dozen grade A large eggs averaged $2.27 in September 2026. The record so far is $6.23 in March 2025; prices spiked in 2023 and 2025 when bird flu cut the number of laying hens. Prices are BLS averages across US cities since 1980, when this series begins, in dollars of the day, not adjusted for inflation. October 2025 is missing because a lapse in federal funding stopped data collection.

How much does each country spend on health care per person?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2023, the United States spent $13,473 per person on health care, about 10 times the world figure of $1,317. Germany spent $6,395, Japan $3,638, China $763 and India $85; Madagascar spent the least, $17. Search 191 countries and territories. Spending counts what governments, insurers and households paid for health care, but not new hospitals or equipment, in US dollars at each year's exchange rates, not adjusted for differences in prices.
How to read this chart
Each bar is what a country spent on health care in a year, by governments, insurers and households together, divided by its population and turned into U.S. dollars. The dashed line is the world. The figures aren't adjusted for prices, so a dollar buys more care in some countries than others.
Questions to discuss
- About how many times the world figure does the United States spend per person?
- Does spending more on health care per person always mean people live longer? What other chart on Chartly could help you check?
- Doctors and nurses are paid less in some countries. How would that change what these dollar figures can tell you?
