This paper uses a unique data set of the Human Development Index to describe long-run human development trends for 111 countries, from 1970 to 2005. The first part of the paper shows trends by region, period and index subcomponent. The life-expectancy and education subcomponents grow faster than income. The assessment of HDI progress is sensitive to choice of measurement. The second part of the paper focuses on the differences between income and non-income determinants of human development.
