The definitions of poverty and income inequality, how technology and trade raised demand for high-skilled labour while lower-skilled workers face a large supply, and the high poverty rate among single-parent households — Principles of Economics 2e, OpenStax, licensed CC BY 4.0. https://openstax.org/books/principles-economics-2e/pages/15-4-income-inequality-measurement-and-causes and https://openstax.org/books/principles-economics-2e/pages/15-1-drawing-the-poverty-line. Changes: the US household, college-degree and census figures dropped; the skills argument kept as demand and supply for lower-skilled labour without the winner-take-all figures; "the poverty rate among single-parent households tends to be relatively high" kept, with the reason (one adult both earns and cares) ours; the grouping into five causes and three links (wage, hours, household size) is ours; British spelling.
