Perfect Capita · The new GDP

A prosperous nation is one that reaches every person.

GDP tells a nation how much it produces. It cannot tell a nation whether that prosperity reaches everyone. Perfect Capita can.

PERFECT CAPITA, DEFINED

The yearly cost, per person, of delivering all Seven Human Guarantees to everyone in a nation.

GDP per capitaWhat a nation produces, per person.

Perfect CapitaWhat it costs, per person, to reach everyone.

The distance between the two is what Capital Architecture is designed to finance.

The Seven Human Guarantees

Seven conditions of a dignified life.

What every nation should make possible for every person. Choose a guarantee to read its promise, how it is measured and how each nation costs it.

GUARANTEE 01 OF 07

Food

Every person can eat nutritious food, every day, throughout life.

Measured as: The share of people who can afford a healthy diet.
Costed, nation by nation, from: A local, nutritious food basket.

Three numbers for every nation

One measure, two companions.

Every Perfect Nations blueprint reports the same three numbers, so any nation can be read against any other.

THE MEASUREPerfect Capita
The yearly cost, per person, of delivering all seven guarantees to everyone, set in the nation’s own prices.
Split between what households pay, what public budgets carry and what new capital must finance.
COMPANION ICoverage
How fully the seven are delivered today, out of 100. A nation’s score is its weakest guarantee.
Each guarantee is measured strictly, from published international and national data.
COMPANION IIThe Gap
The people still short of a guarantee, and the yearly cost of reaching them.
The Gap is the brief for Capital Architecture: the instruments that close it.

The weakest-guarantee rule

A nation is only as strong as the guarantee it provides least.

No nation can make up for failing in health by excelling in education. Averages hide the people left out; Perfect Capita does not. Coverage is set by the weakest of the seven, so every guarantee must be met.

Illustration. Health has the widest gap to full coverage, so Health sets the nation’s Coverage.

It has been done

Five nations. Real progress.

Every guarantee has already been delivered at national scale somewhere in the world. Perfect Capita asks for all seven, in every nation.

Where Perfect Capita fits

Built to stand beside the frameworks nations already use.

A proposed contribution to the development agenda beyond 2030: it complements the Sustainable Development Goals and GDP, and goes one step further by costing and financing the floor.

The SDGsWhat the world seeks to achieve: 17 goals and 169 targets.
The Seven Human GuaranteesWhat every person should receive: seven, measured person by person.
GDP per capitaHow much an economy produces.
Perfect CapitaWhether that prosperity reaches everyone, and what it costs to make sure it does.
Multidimensional povertyWhich deprivations people experience.
The GapWhat it will take, in people and in money, to end those shortfalls.
Development financeHow money is mobilised.
Capital ArchitectureHow the seven guarantees are financed, from a nation’s own assets.

How it is set

One framework for the world. One price for each nation.

PERFECT NATIONS SETSThe framework

What each guarantee means, the minimum it requires, and how achievement is measured. The same seven, measured the same way, in every nation.

EACH NATION SETS, WITH USThe price

What it costs to deliver the seven in that nation, in its own prices, from credible data and open assumptions. No single dollar figure is imposed on Afghanistan, Barbados or Rwanda.

Guarantee	Measured, in every nation, as	Costed, in each nation, from
Food	The share of people who can afford a healthy diet.	A local, nutritious food basket.
Water	The share of people with safely managed water and sanitation.	Connection, treatment and running costs.
Shelter	The share of people in safe, adequate, affordable housing.	Housing and the infrastructure around it.
Energy	The share of households with reliable electricity and clean cooking.	The cost of household energy services.
Education	The share of people reaching and completing quality education.	The cost per learner.
Health	Coverage of essential care without financial hardship.	Health services and financial protection.
Livelihoods	The share of people with enough earned income or income protection.	A living-income benchmark and the social protection gap.

The first nation measured

Barbados: 69 of 100, held by food.

Barbados delivers water, shelter and energy to almost everyone. About three in ten Barbadians are moderately or severely food insecure, so food sets its Coverage. The blueprint shows the full wheel, its sources and the instruments that could close the Gap.
