How hexplace measures places

Every number on hexplace comes from a public dataset, is calculated the same way for every town, and says how precise it is. Where good data doesn't exist, the page leaves that measure out.

From raw data to a town page

  1. 01CollectOpen datasets are downloaded as published and kept unchanged.
  2. 02StandardiseEach dataset is converted into a standard table.
  3. 03MeasureThe measures for every town are computed from those tables.
  4. 04DeriveScores, "who it suits" verdicts and notable facts come from the measures.
  5. 05CheckQuality checks run first. A release that fails them is not published.
  6. 06PublishEach release is frozen, so a page always shows one consistent set of data.

Precision labels

Scores

Each score runs from 0 to 100. Every input becomes a percentile among the towns in the country, and the percentiles are averaged with these weights. A score is left blank when less than 60% of its weight has data.

ScoreInputs and weights
Climate comfortJanuary high 30% (higher is better) · Days above 35°C 25% (lower is better) · Days with rain a year 20% (lower is better) · Tropical nights 15% (lower is better) · Frost days 10% (lower is better)

Access to servicesNearest hospital 35% (lower is better) · Nearest airport 20% (lower is better) · Grocery stores on foot 20% (higher is better) · Doctors on foot 15% (higher is better) · Schools on foot 10% (higher is better)

"Who it suits" rules

A verdict appears only when every condition holds. If a value in the condition is missing or too coarse, the verdict does not appear.

ERA5-Land reanalysis

The Copernicus reanalysis of hourly weather on a grid of about 9 km. Daily highs and lows are taken from hourly temperatures, and monthly averages cover 1991-2020.

How it is used, and its limits

Each town uses the nearest grid cell that is mostly land, because cells that are mostly sea understate the gap between day and night. Temperatures are then adjusted from the cell's average height to the town's height at 6.5°C per kilometre.

Before a release, the results are checked against official station averages, with a tolerance fixed before any result was seen. A release whose climate misses these checks is not published.

Corrections

Corrections are made in the data pipeline, so they reach every affected page with the next release.
