This wave of mining activity would decline in the mid-20th century, causing the deterioration of the state's economy, especially in the Pachuca area. In the 1950s and 1960s efforts were undertaken to shift the state's economy from agriculture and mining to manufacturing. In 1952, an automotive motor production facility called Diesel Nacional (DINA) was constructed. The old Instituto Científico Literario Autónomo de Hidalgo was converted to the Universidad Autónoma del Estado de Hidalgo in 1961, with the purpose of turning out engineers and other professionals to provide the impetus for the development of industry. These efforts soon paid dividends and construction growth, especially of suburban subdivisions for workers in newly built factories.
