Counting lives.
Measuring poverty.
Mapping trajectories.
Two intertwined projects: a history of poverty measurement as political act, and topological data analysis revealing the shapes poverty leaves in data.
A historical investigation into the politics of poverty measurement — from Rowntree's dietary surveys to modern multidimensional indices. This book traces how numbers about the poor have always carried the values of those who made them.
Explore Counting Lives →A programme of topological data analysis applied to longitudinal UK household panel data. Ten linked papers applying Mapper, persistent homology, and graph-neural-network methods to employment and poverty trajectories.
Explore the TDA Research Programme →This chapter traces how Orshansky's 1963 poverty matrix — a transparent, household-specific measurement instrument — was standardised and simplified by the Bureau of the Budget in 1969 into a single administrable threshold, severing it from its material grounding, and how that institutional move is replicated in Universal Credit's standard allowances today.
