Assuming it takes about 1 second to count each dollar, it would take one billion seconds, or about 31 years and 8 months.
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.
