In Europe since the Seventies, Jeremy Black offers a succinct and authoritative analysis of the social and economic development of Europe in recent decades.             While providing a full treatment of environmental, demographic, and cultural issues in Europe, Black also offers delineations of broader political, economic, and social matters discussing practical, immediate subjects like migration, crime, transportation, and the environment. Europe since the Seventies reveals how European society has changed strikingly--former societal lines drawn on the basis of economics and class have given way to lines formed by identity, such as gender, sexual orientation, and ethnicity. Meanwhile, the European Union has created an expanded Europe and is now a testing ground for new forms of economics and politics.             A readable, concise, and timely work, this latest book by a notable European historian will be indispensable to anyone wishing to understand the complexities of present-day Europe.
