Dixon examines the social security systems of 172 countries. Focusing on the diverse array of approaches existing today, he explores global social security patterns, recent developments, and future issues, and he assesses and ranks social security programs and systems. By providing a global perspective on social security, Dixon enables scholars, students, and social security administrators to place national and perhaps regional social security policy debates into their larger, regional and global settings. The volume is intended for scholars and graduate students in the broad fields of social work, social welfare, and social security.
