Описание:

A 'baby boom' is a period marked by a significant increase of birth rate. This demographic phenomenon is usually ascribed within certain geographical bounds. People born during this 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. The causes of baby booms involves various fertility factors. The most well-known baby boom occurred immediately after World War II during the Cold War. It was a change of trend that was largely unexpected, because in most countries it occurred in the midst of a period of improving economies and rising living standards.
