Final answer:
The population of New York City has changed over time, with figures like 1,174,800 in 1860, 1,912,000 in 1880, and 3,437,000 in 1900. The most up-to-date figure requires the latest data from the U.S. Census Bureau. As of 2017, the population of the United States exceeded 325 million people.
Step-by-step explanation:
The population of New York City has fluctuated significantly throughout history. For instance, back in historical census years like 1860, 1880, and 1900, the population of New York City was 1,174,800; 1,912,000; and 3,437,000 respectively. However, these historical figures don't reflect the current population. The U.S. Census Bureau periodically provides updated population figures. As per recent (post-2000) updates, the population of the United States as a whole has seen considerable growth, with more than 325 million people. This makes it the third most populated country globally, and as of 2017, the U.S. had already surpassed the 325 million mark. To get the specific current population of New York City, the best resource would be the latest data from the U.S. Census Bureau or local demographic statistics from New York City's government. While exact figures might vary by source and update frequency, in general, New York City remains one of the most populous cities in the United States.
