To determine how many people live in urban areas in North America, we would typically reference the most recent statistics available from a reliable source, such as the United Nations or the World Bank.
If recent data suggests that 3 out of every 4 people in North America live in urban areas, we can interpret this as a ratio. This ratio implies that for every 4 people in North America, 3 are living in urban areas, which is a proportion of 3 out of 4, or 75%.
Therefore, based on the assumption that this data is correct, the answer would be that 3 out of 4 people in North America live in urban areas.
