employees had also begun to commute. Farther east in the highly developed department of Maldonado lies the major resort of Punta del Este. This has been developed as a fashionable playground more for Argentines than for average Uruguayans, who found it too expensive. With its hotels, restaurants, casino, and nightclubs, Punta del Este was a major export earner, and it dominated Uruguay's tourism industry. Vacationing Uruguayans of more modest means were concentrated in smaller resorts such as Piriápolis and Atlántida, which are closer to Montevideo. Beyond Punta del Este in the still mostly undeveloped department of Rocha, a number of communities had sprouted along the unspoiled Atlantic coast with its kilometres of sandy beaches and huge breakers. These small vacation communities—such as Aguas Dulces and Cabo Polonio, both in Rocha Department—were entirely unplanned and lacked essential services. In many cases, simple holiday chalets had been built on public property adjoining the seashore without any legal title to the land. In 1990 the authorities in Rocha Department announced plans to regulate and improve this development in hopes of encouraging visits by higher-spending tourists. Regional development Uruguay's regions differed markedly not only in population size and density but also in their indexes of social and economic development, including education, health care, communications, energy consumption, and industrialization. Least developed were the northern ranching departments along the Brazilian border—Artigas, Rivera, and Cerro Largo—and also Tacuarembó. Somewhat more developed was a band of six departments stretching across the center of the country, from west to east: Río Negro, Flores, Florida, Durazno, Treinta y Tres, and Rocha. More industrialized and urbanized, but still quite poor, were the departments of Soriano and Salto, which, as noted previously, benefited from the construction of a bridge and a dam, respectively, across the Río Uruguay in the late 1970s and early 1980s. The two remaining western departments—Colonia and Paysandú—were the most developed of the littoral. Three departments close to Montevideo—San José, Canelones, and Lavalleja—presented a contradictory picture of relatively advanced economic development combined with low indexes of social modernization. Finally, Montevideo and the department of Maldonado (which is strongly affected by the tourism industry in Punta del Este) had the highest indexes of social and economic development in the country.
