D. creation of a youth culture in the 1960s

Explanation:

The baby-boom was a demographic phenomenon that occurred after WWII, between 1946 and 1964, characterized by an increase in the birthrate. This increment was due to the unprecedented global economic growth that followed the war. Consequently, the young range of the population was larger during the 50s and 60s, which combined with economic development, created a new branch of consumers in the market: teenagers and young people. The new teenagers, most of them from the middle class who had access to jobs, demanded new cultural goods, like rock music, comics, movies, art, etc. Young people did not only entered in the public sphere as passive consumers, but also as active members of the civil society, demanding for different politics towards sex, drugs, the Vietnam war, civil rights, women rights, and against the Cold War, and the Nuclear race, among other things. This created a totally new youth culture during the 60s, giving place to the hippie wave and counter-culture movement that characterized the second part of the 20th century.
