The number is made in somebody’s front room
Behind a headline poverty figure is an enumerator at a door with a questionnaire. Every property of the number — its coverage, its comparability, its uncertainty — starts there.

Where the texts were agreed
Rome set the agenda, Paris numbered it, Accra sharpened it, Busan replaced it
The Rome Declaration on Harmonisation of 2003 flagged duplication; Paris attached targets to it; Accra added transparency and predictability; Busan brought in providers outside the OECD Development Assistance Committee and revised the indicators, which is why the two monitoring series are not straightforwardly comparable.
“The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income.”

The number is made in somebody’s front room
A published figure does not say whether it was measured or estimated
Where a household survey exists, the number is counted. Where none exists, it is modelled from whatever is available and printed in the same column, in the same typeface, with the distinction surviving only in a footnote. A rebasing of national accounts can move a headline figure substantially without anything real having changed.
Behind every international estimate is a sampling frame, a questionnaire and an enumerator at a door. Every property of the number starts there.

Modelled against measured
Where no survey exists the figure is estimated, and published series rarely make that distinction visible.

The offices that publish it
National statistical offices, not international agencies, produce most of the underlying data — and their capacity varies enormously.

Eight goals with deadlines
The MDGs ran from 2000 to 2015 and were the first time the field agreed on a short numbered list with dates attached.
A target that is measured gets managed; one that is not, does not. That is the central criticism of the framework and also the central point of it.
