<P> 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 . </P>
