Final answer:
Puerto Rico is the smallest of the Greater Antilles and part of the US commonwealth, potentially leading to fewer nonresident tourists compared to the larger islands like Cuba and Jamaica, which are known for tourism, and the Dominican Republic, which has industrial growth.
Step-by-step explanation:
To determine which country of the Greater Antilles had the fewest nonresident tourists, we can consider the available information about tourism and economic development on the islands, recognizing that such data can fluctuate year by year and may depend on various factors.
Cuba, being the largest island with diverse geography and a history of colonialism and revolution, is an attractive tourist destination. The island is also known for its attractive Caribbean beaches. Although it attracts tourists, political and economic circumstances might affect its tourist numbers.
Jamaica is physically smaller and has a history of Spanish and English colonization with a plantation economy. As a popular destination, Jamaica is well known for its cultural heritage and music, potentially attracting significant numbers of tourists.
Puerto Rico, as the smallest of the four and part of the US commonwealth, with US citizenship for its residents, might have more traffic due to easy travel from the US, yet this does not necessarily translate to nonresident tourism.
The Dominican Republic has experienced growth in light industries and information technologies, which may not directly correlate with tourism but could indirectly support an increase in tourists.
Given the data, a safe assumption might be that Puerto Rico, being the smallest with close ties to the United States, might have fewer nonresident tourists in comparison to destinations like Cuba and Jamaica, known specifically for tourism, and the Dominican Republic, which has shown industrial growth.
Please note that definitive current figures would be required for an accurate answer.
