Birth year · Generation Gamma · 2040–2054
Projected to arrive in a world of 9.58 billion people, where women are projected to have 2.1 children on average and about 133.8 million babies are born a year.
A baby born in 2048 is expected to be Generation Gamma, the cohort McCrindle sets at 2040–2054. They will turn 18 in 2066 and 30 in 2078. Roughly 133.8 million babies are projected to be born worldwide that year (UN medium-variant projection).
2048 has not happened yet, so this page carries no events — only what follows arithmetically from a 2048 birth year. We do not invent history, forward or back.

The cohort this year belongs to
Generation Gamma is the cohort expected after Generation Beta: babies born from 2040 to 2054, in the sequence McCrindle has set out. Nobody in it has been born yet.
Cohort boundaries are hard lines drawn through a continuous thing. A child born a day before or after one of them lands in a different generation with an identical childhood.
They are expected to be Generation Gamma, which McCrindle, the research firm that named Generation Alpha and Generation Beta, sets at 2040 to 2054. It is a name set out in advance: nobody in it has been born yet.
Nobody born in 2048 exists yet — the year is still ahead. They would turn 18 in 2066.
About 133.8 million worldwide, projected by the UN medium variant.
Between 2052 and 2055, depending on the country. The United Kingdom and Ireland start at four, most countries at six, and Sweden, Poland and Indonesia at seven.
In 2066.
In most US states, class of 2066 if born January to August and class of 2067 if born September to December, because 1 September is the most common kindergarten cut-off. In England and Wales they take A-levels in the summer of 2066 (born January to August) or 2067 (born September to December).
About 9.58 billion, in the UN World Population Prospects 2024 medium-variant projection, with 2.11 children per woman worldwide.
