The perception of the impact of tourism on the resident population is the key to the tourist industry. The tourist development of the Mediterranean coast has led to a population explosion where the largest figures are of non-national origin, which have become the majority, ahead of the Spanish population. Nationality in the perception of the host population has been overlooked, but this is an important factor in Torrevieja (Spain), where more than 50% of the host population is non-national. Our finding confirms that these two host groups, national and non-national, have different perceptions of the impact of tourism in the area.
