A memo you can forward: why fertility matters, how this country compares with its neighbors, and how many working-age people versus retirees the pyramid already implies. Tick sections, park each chart next to the paragraph it belongs with, then generate — or start from blank headings and write it yourself. After that, every heading and paragraph is editable, and Expand / Tighten / Ask AI can rewrite one section at a time.
National fertility, age structure, and migration set the size of the next workforce and the next electorate.
AI prose uses the same OpenAI key as Cohort — add billing credits at platform.openai.com if generate or Expand fails. Limited to a few memos per hour. You can always type over the text.
This briefing will cover
Period TFR versus replacement (~2.1) is the first number — then who is having the children, if an official split exists.
Neighbors on the same World Bank series are the “ah, they have X children” chart.
2040 workers are mostly already born; TFR shows up around 2060. Who works, retirement age, and migration move 2040.
Family policy elsewhere (France, Hungary, Korea) has not returned a high-income country to replacement in recent decades.
Working-age counts are modeled from today’s pyramid. 2040 taxpayers are mostly already born; TFR shows up around 2060.
