In the problem, we are given the following information:

- The world population was approximately 7 billion.
- Of these, 2.03 billion people wanted to stay in their country, which means 7 billion - 2.03 billion = 4.97 billion people wanted to move.
- Out of 71 people surveyed who wanted to move, 23 of them said they would like to move to the United States.

We are asked to find how many people out of the 4.97 billion would choose the United States. 

The proportion of people who want to move to the United States is:
\[
\frac{23}{71}
\]

Now, we calculate the number of people who would choose the United States:
\[
\text{People moving to the US} = 4.97 \times \frac{23}{71}
\]

Let me calculate that for you.Approximately 1.61 billion people, out of the 4.97 billion who want to move, would choose to move to the United States.

Do you want further details or have any other questions?

Here are five related questions:
1. What proportion of people wanted to move to Canada and Great Britain combined?
2. How would the number change if the total population were different?
3. How is the proportion calculated from survey data?
4. What might affect people's decisions to move to a particular country?
5. How could you estimate the margin of error in the survey?

**Tip:** Always double-check proportions to ensure accurate representation of survey data when applied to larger populations.

A survey was conducted when the world population was about 7 billion, and 2.03 billion people wanted to stay in their country. Among those in the survey that said they wanted to leave their current country, 23 out of 71 said they'd like to move to the United States. How many of the people who want to move would choose the United States? Round to the nearest hundredth.

This problem uses survey data to calculate how many people would move to the US out of a population of 4.97 billion. Learn how to apply proportions and multiplication to solve the problem. Suitable for Grades 6-8.
