This document discusses different ways to measure development levels in countries including GDP, birth rate, death rate, GNP/GNI, and the Human Development Index (HDI). HDI is considered one of the best measures as it takes a broader view of development beyond just economic measures by also including factors like life expectancy, education levels, and income. A scattergraph can show correlations between different development measures. Students are tasked with completing a table matching development measures to their definitions and effects as a country develops, as well as activities analyzing scattergraphs and answering past exam questions.
