where did the term baby boomer come from
Baby boomers The phrase baby boom refers to a noticeable increase in the birth rate. The post-war population increase was described as a "boom" by various newspaper reporters, including Sylvia F. Porter in a column for the May 4, 1951, edition of the New York Post, based on the increase in the population of the U.S. of 2,357,000 in 1950.[8] According to the Oxford English Dictionary, the first recorded use of "baby boomer" is in 1970 in The Washington Post.[9] Various authors have delimited the baby boom period differently. Landon Jones, in his book Great Expectations: America and the Baby Boom Generation (1980), defined the span of the baby-boom generation as extending from 1943 through 1960, when annual births increased over 4,000,000. Authors William Strauss and Neil Howe, well known for their generational theory, define the social generation of Boomers as that cohort born from 1943 to 1960, who were too young to have any personal memory of World War II, but old enough to remember the postwar American High.[10]
Demographic transition Demographic transition (DT) is the transition from high birth and death rates to lower birth and death rates as a country or region develops from a pre-industrial to an industrialized economic system. The theory was proposed in 1929 by the American demographer Warren Thompson,[1] who observed changes, or transitions, in birth and death rates in industrialized societies over the previous 200 years. Most developed countries have completed the demographic transition and have low birth rates; most developing countries are in the process of this transition.[2][3] The major (relative) exceptions are some poor countries, mainly in sub-Saharan Africa and some Middle Eastern countries, which are poor or affected by government policy or civil strife, notably, Pakistan, Palestinian territories, Yemen, and Afghanistan.[2]
