Period marked by a significant increase of birth rate
the concept of a baby boom
A baby boom is a period marked by a significant increase of births. This demographic phenomenon is usually ascribed within certain geographical bounds of defined national and cultural populations. The cause of baby booms involves various fertility factors. The best known baby boom occurred in the mid twentieth century, sometimes considered to have started after the end of the Second World War, sometimes from the late 1940s, and ending in the 1960s. People born during this period are often called baby boomers.

"According to the new UNICEF report, almost 2 billion babies will be born in Africa between 2015 and 2050 and the 2 main driving forces behind this surge in births and children are continued high fertility rates and rising numbers of women able to have children of their own." By 2050, Africa is predicted to account for about 55% of all births in the world, 40% of all children under the age of five, and 37% of all children worldwide (under 18). Africa will become more crowded as its population continues to grow, considering the continent is predicted to grow from 8 people per square kilometer in 1950 to 39 in 2015, and to around 80 by the middle of the century. The HIV/AIDS crisis in Africa has contributed to a population boom. Aid money used for contraception has been diverted since the start of the AIDS crisis in Africa into fighting HIV, which has led to far more births than AIDs has killed. Africa accounted for one out of every nine births in the world in 1950. It is predicted that they will account for approximately one in every three global births by the year 2030. Africa would account for almost half of all births by the end of the century. While Aboriginal fertility has remained higher than the overall Canadian birth rate, it has decreased from four times in the 1960s to one and a half times today. According to Statistics Canada, demographic change was just a part of the reason for the increase in Aboriginal population in the last half of the century, with more complete census taking and increased numbers of people identifying as Aboriginal also playing a role. In 2011, the children of baby boomers made up 27% of the total population; this category was called Generation Y, or the "baby boom echo". The fertility rate of the generations after the baby boomers dropped as a result of demographic changes such as increasing divorce and separation rates, female labour force participation, and rapid technological change. In addition to having the highest fertility rate among developed nations, it is the only developed country to have never had a sub replacement fertility rate. Israel's baby boom began in 1947, a year before independence, when the fertility rate among the Yishuv, or Jewish population of what was then Mandatory Palestine, began to rise dramatically as a result of the aftereffects of the Holocaust and expectations of Jewish independence.

Ireland has a much younger population compared to Europe overall, with one in four people under age 15. This is likely due to the baby boom experienced in the late 2000s and early 2010s, after the Great Recession. The number of births in Ireland reached a 118 year high in 2009 when the economy experienced its worst year on record. The number of births had remained stable with 74,650 babies born in 2012, higher than the 65,600 average during the Celtic Tiger (1995–2007), despite the struggle to emerge from financial crisis.

The number of births in Ireland rose by more than 3,000 in 2021 after being in decline for more than a decade, implying the COVID 19 pandemic triggered a baby boom in Ireland. Health Service Executive figures show 59,874 babies were born in maternity hospitals and units in 2021, up from 56,858 the previous year, which could continue into the early 2020s. It is the first time that there has been an annual increase since 2009, when there were 75,554 births registered.

In Japan, the first baby boom occurred between 1947 and 1949. Although there are no official statistics for 1945 and 1946, the number of births in 1946 is estimated to be around 1.6 million. Therefore, it is not appropriate to set the beginning of the baby boom to 1946. Changes in the number of births in Japan Teikoku shoin Co., Ltd. The trend is the same, although there are annual numbers that are slightly different from official vital statistics. Note that the number of births in 1946 is 15.7 million. The number of births in this period exceeded 2.5 million every year, bringing the total number of births to about 8 million. The 2.69 million births in 1949 are the most ever in postwar statistics. The number of births in 1949 does not include the number of births in Okinawa prefecture before return to the mainland. The cohort born in this period is called the "baby boom generation" (団塊の世代, dankai no sedai, means "the generation of nodule").

A period of more than two million annual births from 1971 to 1974, with the number of births in 1973 peaking at 2.09 million, is referred to as the second baby boom. However, unlike the first boom, this increase in the number of births is an increase in the number of births not accompanied by an increase in the total fertility rate. The people born during this period are often called "baby boom juniors" (団塊ジュニア, dankai junia, means "the juniors of the generation of nodule").

Decreței: (1967–1989), A ban on abortion and contraception caused a baby boom in Romania, leading to overcrowded hospitals. According to an article in the Chicago Tribune on December 26, 1967, a doctor had to beg a woman to give birth at home due to overcrowding at the hospital. The article also said that "pregnant women were having to share hospital beds, and sickly babies were being put into oxygen tents in groups." The baby boom in Romania caused problems that began affecting the health of the nation. Before its ban in 1967, abortion was the only form of birth control. The ethno nationalistic policies of Romania's leader, Nicolae Ceaușescu, further contributed to the baby boom. To encourage people in dominant ethnic groups to have more children, the Romanian Government established financial incentives to have children, including a tax for anyone over 25 without a child. This motivated many people to have children at a younger age, and with ethnic Romanian partners, leading to a surge in births, which later dropped to 14.3 births per 1000 individuals by the 1980s. In an effort to increase birth rates, Ceaușescu changed the legal age to marry to 15, launched media campaigns, and mandated monthly gynecological examinations of all women of childbearing age. This caused a near fivefold increase in spending on incentives, but the birth rate decreased by 40%.

The number of annual Russian births hit a low in the 1990s and early 2000s, following the collapse of the Soviet Union and the 1998 financial crisis. However, the following years saw the birth rate rise rapidly. By 2012, the number of births outnumbered deaths for the first time since the Soviet Union. To many Russians, this was not only a sign of economic prosperity, but also a recovery from the poverty and social decline following the downfall of the Soviet Union.

After the fall of the Soviet Union in 1991, the Ukrainian birth rate reached a low of 1.14 births per women in 2003. Following the Orange Revolution, the total fertility rate gradually elevated, eventually to a peak of 1.49 births per women in 2014. However, this did not last, as the birth rate rapidly diminished following the Invasion of Crimea in 2014.

Probably due to the ongoing Russian Invasion of Ukraine, the birth rate in Ukraine has declined significantly in 2022, down to 1.2 1.3 per woman. Despite this, there could very well be a baby boom after the war ends, with the fertility rate projecting to reach 1.60 births per women by 2030. However, the millions of refugees and emigrants fleeing since the Russian Invasion will keep the overall population falling short of what it was before the war for at least a few decades, despite the baby boom.

The baby boomers are commonly defined as the generation born after the Second World War, generally from 1946 to 1964. However, this definition of baby boomers is based on American demographic trends which saw a surge in births post Second World War that was sustained into the 1960s. In the UK, the post Second World War surge in births was confined to a sharp spike in 1946, after which the number of births dropped again. Then the post World War babies started having their babies, giving rise to the births that can be seen across the 1960s. Due to the different demographic profile seen in the UK compared to America, British people usually define as those born between 1960 and 1969 (inclusive) as baby boomers. As of 2021, baby boomers make up about 20% of the British population, which is about 14 million people. Baby boomers today are certainly one of the most powerful and wealthy generations in the United Kingdom. For example, in 2020, growth in online shopping was led by baby boomers.
