A baby boom is any period marked by a greatly increased birth rate. This demographic phenomenon is usually ascribed within certain geographical bounds. People born during such a period are often called baby boomers; however, some experts distinguish between those born during such demographic baby booms and those who identify with the overlapping cultural generations. Conventional wisdom states that baby booms signify good times and periods of general economic growth and stability; however in circumstances where baby booms lead to very large number of children per family unit, such as in the case in lower income regions of the world, the outcome may be different. One common baby boom was right after WWII during the Cold War.

The HIV/AIDS crisis in Africa has contributed locally to a population boom. Aid money used for contraceptives has been diverted over the past two decades into fighting HIV, with the number of babies born far outstripping the deaths from AIDS.
France experienced a baby boom after 1945; it reversed a long-term record of low birth rates. The sense that the population was too small, especially in regard to more powerful Germany, was a common theme in the early twentieth century . Put in a list policies were proposed in the 1930s, and implemented in the 1940s.
In addition, there was a steady immigration, especially from former French colonies in North Africa. The population grew from 41 million in 1946, to 50 million in 1966, and 60 million by 1990. The farm population decline sharply, from 35% of the workforce in 1945 to under 5% by 2000. By 2004, France had the second highest birthrate in Europe, behind only Ireland.

United StatesThe term "baby boom" most often refers to the post–World War II baby boom (1946–1964) when the number of annual births exceeded 2 per 100 women (or approximately 1% of the total population size). There are an estimated 78.3 million Americans who were born during this demographic boom in births. The term is a general demographic and is also applicable to other similar population expansions.
Recent baby boom periods include the following:
- Post–World War I baby boom: (1918-1929)
- Post–World War II baby boom: Years of duration vary, depending on the source.
- Echo baby boom (Millennial Generation): (researchers and commentators use birth years ranging from the early 1980s to the early 2000s) are the children of the baby boomers, Gen Xers, and even some members of the Silent Generation.
