The Office for National Statistics has described the UK as having had two baby booms in the middle of the 20th century, one in the years immediately after World War II and one around the 1960s with a noticeably lower birth rate (but still significantly higher than that seen in the 1930s or later in the '70s) during part of the 1950s. Bernard Salt places the Australian baby boom between 1946 and 1961. In the US, the generation can be segmented into two broadly defined cohorts: the "leading-edge baby boomers" are individuals born between 1946 and 1955, those who came of age during the Vietnam War and Civil Rights eras. This group represents slightly more than half of the generation, or roughly 38,002,000 people. The other half of the generation, usually called "Generation Jones", but sometimes also called names like the "late boomers" or "trailing-edge baby boomers", was born between 1956 and 1964, and came of age after Vietnam and the Watergate scandal. This second cohort includes about 37,818,000 people. Others use the term Generation Jones to refer to a cusp generation, including early Generation X years, with a typical range of 1954 to 1965. Demographics Asia During the time of the Great Leap Forward, the Chinese Communist Party (CCP) encouraged couples to have as many children as possible because it believed a growing labor force was needed for national development along socialist lines. China's baby-boom cohort is the largest in the world. According to journalist and photographer Howard French, who spent many years in China, many Chinese neighborhoods were, by the mid-2010s, disproportionately filled with the elderly, to whom the Chinese themselves referred as a "lost generation", who grew up during the Cultural Revolution, when higher education was discouraged and large numbers of people were sent to the countryside for political reasons. As China's baby boomers retire in the late-2010s and onward, the people replacing in the workforce will be a much smaller cohort due to the one-child policy. Consequently, China's central government faces a stark economic trade-off between "cane and butter"—how much to spend on social welfare programs such as state pensions to support the elderly and how much to spend in the military to achieve the nation's geopolitical objectives. According to the National Development Council of Taiwan, the nation's population could start shrinking by 2022 and the number of people of working age could fall 10% by
