Public opinion is a global conversation. Thanks to data providers like Afrobarometer, Market Analysis (Brazil), and Central Asia Barometer, researchers can track democratic will and development priorities across continents.

The mysteries of column binary revealed! Converting punch-card data files to today’s stats formats can unlock decades-old data for publication. Roper provides everything you need to convert whole datasets or just the variables you need.
