MONEY / MEASUREMENT CLUSTER

GDP and economic measures

Build a careful route from the GDP indicator and its institutional metadata to total-versus-per-person comparisons, percentage change and a game about choosing the measure that fits the question.

THE CENTRAL QUESTION

What does an economic number measure, and what must be added before it can support the conclusion?

QUESTIONS TO CARRY

Do not lose these checks.

01
Is the figure nominal or adjusted for price change?
02
Is it a total, an average or a distribution?
03
Do the source, year, unit and revision status match across places?

entity / Economic indicatorGDP per capita

GDP per capita divides an economy's gross domestic product by its population. It converts an aggregate into a per-person average, but it still does not show how income is distributed or what a particular household receives.

Italy is a southern European republic extending into the Mediterranean. Its geography, regions, institutions, long historical record and membership of the European Union create many connected routes through the knowledge library.

comparison / KnowledgeNASA vs NIST

NASA and NIST are United States federal organizations that produce public technical knowledge, but their missions and outputs differ: NASA centres on air and space, while NIST centres on measurement science, standards and technology.

Current context

news / EconomyEurostat estimates services production rose 0.8% in May

The release is a useful example of why a percentage needs its time comparison, adjustment method, coverage and revision status before it becomes an economic story.
