Economic Data Literacy: Read the Numbers

Headlines quote GDP growth, inflation, and unemployment daily — but few readers know what those numbers actually measure. This path makes you fluent: reading charts without being fooled, converting between real and nominal, understanding indexes like the CPI, and distinguishing correlation from causation. No advanced math required. By the end you will read an economic news article the way an economist does — asking what is measured, how, and what is missing.

Steps

  1. Step 1: Reading Economic Charts

    Time series, cross-sections, and scatter plots: what each chart type can and cannot tell you.

  2. Step 2: Percentages and Growth Rates

    The language of economic change: percentage points versus percent, and compounding over time.

  3. Step 3: Index Numbers: CPI and Beyond

    How baskets of goods become a single number, and what index numbers hide as well as reveal.

  4. Step 4: Real vs. Nominal

    Adjusting for price changes so you compare purchasing power, not just sticker numbers.

  5. Step 5: Averages and Distributions

    Means can mislead: medians, distributions, and why inequality statistics need both.

  6. Step 6: Correlation Is Not Causation

    Two trends moving together proves nothing about cause — the most abused idea in economic commentary.

  7. Step 7: Spotting Misleading Graphs

    Truncated axes, cherry-picked dates, and missing context: a field guide to chart manipulation.

  8. Step 8: Working With Real Data

    Put it together: read a real economic release, check the definitions, and ask what is missing.
