5.1B Changing Populations

Changing Populations as a Challenge

An HL-only sub-topic: how digital systems deal with populations that are growing, ageing, or on the move.
What makes it a challenge is timescale: age structure is set by birth rates 30 years ago, so today's ageing workforce or youth bulge was locked in long before anyone acted. Pressures (crowded cities, strained pensions, migration) build slowly and cannot be undone by one policy or app.
Framing concepts: space (where people live) and change (how numbers and ages shift). Digital systems both measure the shift and shape the response.
Approach: the challenge up close (counting, ageing, movement), then interventions weighed by what they do, type, effectiveness, and worth (the Paper 3 reasoning).

Counting a Changing World

To respond, a state must first count and identify people, above all through digital ID: an official, often biometric record giving each person a verifiable identity.
A digital ID can unlock benefits, banking, healthcare, and voting, and bring the never-registered into the system for the first time.
1. But it can shut people out when they cannot enrol or their fingerprints will not read, and it gathers sensitive data on a whole population in one place.
Through systems and power, who gets missed decides who a system serves, and the state holding the database gains real power over everyone in it. Contested: a central database can also become a tool for surveillance.
