How did immigration connected to the oil refinery change Aruba’s population?

The establishment of an oil refinery at San Nicolas in the 1920s served as a major catalyst for demographic change on the island. Prior to this development, Aruba’s economy had been relatively weak, but the refinery’s operations led to a dramatic rise in the standard of living.1

This economic shift prompted significant immigration to the island from the United States, Venezuela, Europe, and other parts of the Caribbean. This influx of workers and their families contributed to a substantial increase in Aruba’s total population.1
