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, 22 out of 71 said they'd like to move to the Upited States. The two next-highest proportions were for Canada and Great Britain, each at 7 of 71 .

How many of the people who want to move would choose the United States? Round to the nearest hundredth.
Of the 4.97 billion people who want to move, billion people want to move to the United States.

Step 1 ：First, we need to find out how many people want to move out of their country. We can do this by subtracting the number of people who want to stay in their country from the total world population. So, \(7000000000.0 - 2030000000.0 = 4970000000.0\) people want to move out of their country.

Step 2 ：Next, we need to find out the proportion of people who want to move to the United States. We know that 22 out of 71 people who want to move, want to move to the United States. So, the proportion is \(\frac{22}{71} = 0.30985915492957744\).

Step 3 ：Finally, we multiply the number of people who want to move out of their country by the proportion of people who want to move to the United States to find out how many people want to move to the United States. So, \(4970000000.0 * 0.30985915492957744 = 1539999999.9999998\).

Step 4 ：Final Answer: The number of people who want to move to the United States is approximately \(\boxed{1.54 \text{ billion}}\).
