It took about 12 years for the global population to grow from 1 billion to 2 billion, reaching the latter milestone in 1927. The population reached 1 billion around 1804, and this rapid growth was influenced by advancements in medicine, agriculture, and sanitation during that period.
It took approximately 12 years for the global population to grow from 1 billion to 2 billion, reaching that milestone between 1804 and 1916. In contrast, the population is estimated to take about 13 years to grow from 4 billion to 5 billion, expected to occur between 1974 and 1987. Therefore, it took 1 more year for the population to grow from 4 billion to 5 billion compared to the growth from 1 billion to 2 billion.

If you counted 1 number per second, it would take 220 years to count to 7 billion.
If you counted 1 number per second, it would take at least 220 years to count to 6.9 billion.
