How many eggs are produced worldwide each year?

How to get close to this number

Go through the birds. The explanation gives the number of chickens on Earth, and a laying hen produces on the order of one egg a day for much of the year. Multiply a plausible laying population by a few hundred eggs a year each and the total lands in the trillions. Animal-count times output-rate is the standard route for any agricultural production question.

The per-person framing is the sanity check: roughly two hundred eggs a year for every person alive, which is a number you can weigh against your own consumption. If that feels plausible for a global average — high for some countries, low for others — then the total is credible. Always convert a huge total into a per-person rate before trusting it.

The chicken figure is the more startling one and deserves its own note. There are several times more chickens than humans, making them by far the most numerous bird on the planet, and their combined mass exceeds that of all wild birds together. Domestication has reshaped global biology at a scale that population statistics rarely make visible.
