Charts to read and discuss

Figures as of November 12, 2026, from each chart's current data.

Chart 1 of 3 · Food and drug safety

How many food recalls are for undeclared allergens each year?

The chart's answer: The FDA classified 190 food recalls in 2025 for an allergen left off the label, such as milk, peanuts, tree nuts, wheat, soy, eggs, fish, shellfish or sesame; the most since 2013 was 282 in 2017. From 2013 through 2025, undeclared allergens were the most common reason food was recalled. A recall counts once however many products it covers, in the year FDA first listed it in its weekly Enforcement Report. Chartly sorted FDA's written reasons by their key words; a recall for a germ as well counts under the germ. Meat, poultry and most egg products are USDA's to recall and aren't included. The newest allergen recalls, this year's included, are listed below.

Questions

  1. In one sentence of your own, what does this chart show?

    Open question: answers will vary. Look for answers that use the chart's numbers and source.

  2. Find the biggest change or difference in the chart. What might explain it?

    • 2013 to 2025: up 36 (+23%)
    • Biggest rise from one point to the next: 40, 2022 to 2023
    • Biggest drop from one point to the next: 78, 2018 to 2019
  3. Who collected these numbers, and how recent are they? What else would you want to know before drawing a conclusion?

    • Newest: 190 in 2025
    • Source: U.S. Food and Drug Administration, Enforcement Reports (openFDA food recall data), data as of November 4, 2026

Chart 2 of 3 · Inflation

How fast are US prices rising?

The chart's answer: The inflation rate was 3.7% in September 2026: how much consumer prices changed from the same month a year earlier. Each point makes that comparison, back to 1914, the first year BLS can compare. Inflation peaked at 23.7% in June 1920 and at 14.8% in March 1980; the 9.1% of June 2022 was the highest since 1981. Prices fell as fast as 15.8% a year in 1921 and 10.7% in 1932. BLS collected no prices in October 2025, during a lapse in federal funding, so that month and October 2026 are missing.

Questions

  1. Find two times when inflation was highest. What was happening in the country then?

    • Highest: 23.7% (Jun 1920)
  2. If inflation falls from 8% to 3%, are prices going down, or just rising more slowly?

    • Jan 1914 to Sep 2026: up 1.7 percentage points
    • Biggest rise from one point to the next: 6.1 percentage points, Jun 1946 to Jul 1946
    • Biggest drop from one point to the next: 5.5 percentage points, Jun 1947 to Jul 1947
  3. Find a stretch when the line is below zero. Why might falling prices be bad news for workers and businesses?

    • Jan 1914 to Sep 2026: up 1.7 percentage points
    • Biggest drop from one point to the next: 5.5 percentage points, Jun 1947 to Jul 1947

Chart 3 of 3 · Health

How long do Americans live, and how has that changed since 1900?

The chart's answer: A baby born in the US in 2018 could expect to live 78.7 years, up from 47.3 in 1900. The sharpest drop was in 1918, to 39.1 years, during the influenza pandemic. This CDC dataset stops at 2018; later NCHS reports put life expectancy at 78.4 years in 2023 and 79.0 in 2024, after a fall during the COVID-19 pandemic.

Key numbers (Life expectancy at birth, years)

Questions

  1. Find the sharpest drop on the chart. What happened in the world that year?

    • 1900 to 2018: up 31.4 (+66%)
    • Biggest drop from one point to the next: 11.8, 1917 to 1918
  2. Life expectancy in 1900 was under 50. Does that mean most adults died in their 40s? What else could lower the average?

    • 1900: 47.3
  3. What changes in medicine, food or public health could explain the long rise?

    • 1900 to 2018: up 31.4 (+66%)
    • Biggest rise from one point to the next: 15.6, 1918 to 1919
