Final answer:
The number 3,760,000,000 is written in word form as 'three billion, seven hundred sixty million.' This reflects the substantial growth of the global population, which has been rapidly increasing, particularly since the 20th century.
Step-by-step explanation:
The number 3,760,000,000 in word form is three billion, seven hundred sixty million.
World Population Growth
Looking back at historical data, the world population has undergone significant changes. At the beginning of the 20th century, there were approximately 1.6 billion people. The growth continued and by 1950, the population reached about 3.76 billion. It's intriguing to observe the exponential increase, as by 1960, the population hit the 3 billion mark, and by 1999, it had doubled to 6 billion. According to recent United Nations population projections, the trend continues with the population expected to grow to 9.7 billion by 2050 and potentially 11.2 billion by 2100.
The town example in the provided reference text illustrates the exponential growth by proposing a town starting with 100 people in 1900 and doubling every 10 years could achieve similar numbers to the global population over approximately 260 years. This serves as a simplified model to help grasp the rate of population growth over time.
