Post -- World War II baby boom - wikipedia Post -- World War II baby boom Jump to : navigation , search The end of World War II brought a baby boom to many countries , especially Western ones . There is some disagreement as to the precise beginning and ending dates of the post-war baby boom , but it is most often agreed to have begun in the years immediately after the war , though some place it earlier at the increase of births in 1941 - 1943 . The boom started to decline as birth rates in the United States started to decline in 1958 , though the boom would only grind to a halt 3 years later in 1961 , 20 years after it began . In countries that had suffered heavy war damage , displacement of people and post-war economic hardship , such as Germany and neighboring Poland , the boom began some years later . In May 1951 , Sylvia Porter , a columnist for the New York Post , used the term `` boom '' to refer to the phenomenon of increased births in post-war America .

The trailing boomers are in their late 50s , with the youngest being 57 . In the economy , many are now retiring and leaving the labor force . In 1946 , live births in the U.S. surged from 222,721 in January to 339,499 in October . By the end of the 1940s , about 32 million babies had been born , compared with 24 million in the 1930s . In 1954 , annual births first topped four million and did not drop below that figure until 1965 , when four out of ten Americans were under the age of 20 . In the years after the war , couples who could not afford families during the Great Depression made up for lost time ; the mood was now optimistic . During the war , unemployment ended and the economy greatly expanded ; afterwards the country experienced vigorous economic growth until the 1970s . The G.I. Bill enabled record numbers of people to finish high school and attend college . This led to an increase in stock of skills and yielded higher incomes to families . Definition of the boom years ( edit ) It is important to distinguish between the demographic boom in births , and the actual generations born during that period . United States birth rate ( births per 1000 population ) . The United States Census Bureau defines the demographic birth boom as between mid-1946 and mid-1964 ( red ) . As can be seen by the birth rate chart , the `` birth boom '' of the post -- World War II period is , in a way , as much or more defined by the birth dearths that preceded and followed it , than by any exceptionally high fertility rate . Comparing birth rates from 1946 to 1964 with the rates , say , prior to World War I , the post -- World War II rates are much lower , though they are high in comparison to the time periods immediately preceding and following 1946 - 1964 . The exact beginning and end of the baby boom can be debated . In the United States , demographers usually use mid-1946 to mid-1964 , although the U.S. birthrate began to shoot up in 1941 and to decline after 1957 . By 1958 , the US population increase was back to the pre-Depression increase rate of about 1.5 % per year . Some sources place the beginning as early as 1944 , or according to Strauss and Howe in 1943 . The following table shows changes in US population during the period of US involvement in World War II and for the five years thereafter , based on US census information . Year US resident population ( thousands ) Net change ( thousands ) Percent change 1941 133,121 1,161 0.88 1942 133,920 799 0.60 1943 134,245 325 0.24 1944 132,885 − 1,360 − 1.01 1945 132,481 − 404 − 0.30 1946 140,054 7,573 5.72 1947 143,446 3,392 2.42 1948 146,093 2,647 1.85 1949 148,665 2,572 1.76 1950 151,868 3,203 2.15 10 - year average - 1,991 1.43 Historical and social background ( edit ) This section does not cite any sources .

( March 2017 ) ( Learn how and when to remove this template message ) When the war ended in 1945 , millions of veterans returned home and reintegrated into civilian life . To help this process , Congress passed the G.I. Bill of Rights . This bill encouraged home ownership and investment in higher education through the distribution of loans at low or no interest rates to veterans . Returning veterans married , started families , pursued higher education , and bought their first homes . With veteran 's benefits , the twenty - somethings found new homes in planned communities on the outskirts of American cities . This group , whose formative years covered the Great Depression , was a generation hardened by poverty and deprived of the security of a home or job . Now thriving on the American Dream , life was simple , jobs were plentiful , and a record number of babies were born . Many Americans believed that lack of post-war government spending would send the United States back into depression . However , consumer demand fueled economic growth . The baby boom triggered a housing boom , consumption boom and a boom in the labor force . Between 1950 and 1960 , the nation 's real GDP rose almost 50 % , from $2.2 trillion to $3.1 trillion ( in 2009 dollars ) . The middle class grew and the majority of America 's labor force held white - collar jobs . This increase led to urbanization and increased the demand for ownership in cars and other 1950s and 1960s inventions . Marriage rates ( edit ) Marriage rates rose sharply in the 1940s and reached all - time highs . After World War II , Americans began to marry at a younger age : the average age of a person at their first marriage dropped to 22.5 years for males and 20.1 for females , down from 24.3 for males and 21.5 for females in 1940 . Getting married immediately after high school was becoming commonplace and women were increasingly under tremendous pressure to marry by the age of 20 . The stereotype developed that women were going to college to earn their M.R.S. ( Mrs . ) degree . Family sizes ( edit ) Family size increased sharply throughout the baby boom : the average woman bore 3.09 children in 1950 which increased to 3.65 children per family in 1960 ; the peak was in 1957 , when the figure stood at 3.77 . Most women became pregnant with their first child within seven months of their wedding ; between 1940 and 1960 , the number of families with three children doubled and the number of families having a fourth child quadrupled . In the United States more babies were born during the seven years after 1948 than the previous 30 , causing a shortage of teenage babysitters . Madison , New Jersey , for example , only had 50 high - school girls to babysit for a town of 8,000 , and any sitter could have had two sitting jobs at once if desired . $5 of the $7 that a California couple spent to go to the movies in 1950 went to the babysitter . Easterlin models ( edit ) Economist and demographer Richard Easterlin in his `` Twentieth Century American Population Growth '' ( 2000 ) , explains the growth pattern of American population in the 20th century by examining the fertility rate fluctuations and the decreasing mortality rate . Easterlin attempts to prove the cause of the baby boom and baby bust by the `` relative income '' theory , despite the various other theories that these events have been attributed to . The `` relative income '' theory suggests that couples choose to have children based on a couple 's ratio of potential earning power and the desire to obtain material objects . This ratio depends on the economic stability of the country and how people are raised to value material objects . The `` relative income '' theory explains the baby boom by suggesting that the late 1940s and the 1950s brought low desires to have material objects , because of the Great Depression and World War II , as well as plentiful job opportunities ( being a post-war period ) . These two factors gave rise to a high relative income , which encouraged high fertility . Following this period , the next generation had a greater desire for material objects , however an economic slowdown in the United States made jobs harder to acquire . This resulted in lower fertility rates causing the Baby Bust . In Canada ( edit ) In Canada , the baby boom is usually defined as occurring from 1947 to 1966 , with over 400,000 babies born yearly . Canadian soldiers were repatriated later than American servicemen , and Canada 's birthrate did not start to rise until 1947 . Most Canadian demographers prefer to use the later date of 1966 as the boom 's end year in that country . The later end than the US ( baby - boom generation : babies born from 1946 to 1964 ; see preceding paragraphs ) is ascribed to a later adoption of birth control pills . In australia ( edit ) Bernard Salt places the Australian baby boom between 1946 and 1961 . It is worth noting that Bernard Salt is not a demographer . In the United Kingdom ( edit ) After a short baby boom immediately after the war peaking in 1946 , the United Kingdom experienced a second baby boom during the 1960s , with a peak in births in 1964 , and a third , smaller boom peaking in 1990 . The three peaks can clearly be seen in the UK Population Pyramid . European and south - pacific trends ( edit ) Many European countries , Australia and New Zealand also experienced a baby boom . In some cases the total fertility rate almost doubled . The American birth model , conceived by demographer Frank Notestein , was punctuated by an end to the upsurge in births and a return to pre-war levels . In many European countries the first year of the Post World War II baby boom was the year 1946 , but in Germany the first year was the year 1955 in Finland the largest birth rate was in August and September 1945 . Japan had two separate baby booms . The first started in 1947 , the second in 1971 . Prior to World War II , mortality rates in Europe and America were on a general decline due to improved nutrition and medicine , and a surge in births were previously not experienced at such a large scale . Based on this model , baby boom years for other countries regarded for having a baby boom are as follows : Hungary 's population pyramid in 1960 with boom generations France 1946 -- 1974 United Kingdom 1946 -- 1974 Finland 1945 -- 1950 Germany 1955 - 1967 Sweden 1946 -- 1952 Denmark 1946 -- 1950 Netherlands 1946 -- 1972 Ireland 1946 -- 1982 Hungary 1946 - 1957 Iceland 1946 -- 1969 New Zealand 1946 -- 1961 Australia 1946 -- 1961 Japan 1947 -- 1949 , 1971 -- 1974 In some of these examples , an `` echo boom '' followed some time after as the offspring of the initial boom gave rise to a second increase , with a baby `` bust '' in between . The birth years of the baby boom as noted being both short and long lived , creates what many believe to be a myth to the notion of defining baby boomers as one `` generation '' , as a unified concept is clearly not possible . Indeed , multiple generations may be present in a single country such as Ireland where the boom lasted 36 years . This overlapping effect of generations is not illuminated when considering crude fertility rates . The only common ground for the collective boom is the same approximate starting year . This example can be applied to each state in the United States on an individual basis . The states with a census in place in 1946 saw fertility rates drop to pre-war levels throughout the 1960s , with the average being in 1964 .
