Score: 66/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 96, release rhythm 8, longevity 100
- inputs: {"age_days": 2980, "days_push": 29, "days_rel": 561, "gap_med": null, "n_releases_24m": 1}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The official dataset and methodology code behind The Economist's Big Mac index, released as CSV/Excel files with a Jupyter Notebook showing the calculations. It tracks Big Mac prices, exchange rates, and GDP-adjusted purchasing-power-parity comparisons across countries over time.

## Use cases
- download big mac index data as csv
- compare currency overvaluation across countries
- study purchasing power parity with real-world data
- teach economics with a fun dataset
- analyze historical big mac prices by country
- reproduce the economist's gdp-adjusted index calculations

## When to choose
- you need the authoritative Big Mac index data with full methodology
- you want a clean, well-documented economic dataset for teaching or analysis
- you need historical PPP comparisons maintained by The Economist

## When to avoid
- you need real-time exchange rate data
- you need granular price data beyond Big Macs
- you need a software library rather than a dataset

## Facets
