PIP: This work contains reflections on regional influences in determination of migratory processes, as distinct from economic and political influences at the national level. The relationship between migration and region implies discussion of the concept of regions and regional hierarchies in relation to the national level. The economic structure of a region and its influence on migration for example is related to characteristics of the same phenomenon at the national level. Migration to Mexico City and Monterrey represents a process of social change that affects all of Mexican society, both because of the regional diversity and large volume of migrants to the 2 cities and because of their importance in Mexico's economic and social development. Migration at the regional level may be determined by forces within that region or by processes at the national or even international level that are beyond local control. The particular mix of resources available in a region and the level of its development compared to other places within the nation strongly affect migratory potential. The concrete case of petroleum activity in the state of Tabasco is an example of the lack of participation at the regional level in design of investment policy. The petroleum boom of the 1960s in Tabasco produced profound economic changes in the region and caused changes in the local power structure. Particularities in the case of Tabasco included a state economy dominated by petroleum activity, deterioration in the agricultural sector accompanied by increased livestock raising, expansion of zones of population expulsion especially where livestock were most dominant, and consolidation of strong migratory flows toward the petroleum zones. External factors in the regional socioeconomic situation included the impacts generated by petroleum activity, while internal factors included the increasing importance of livestock and eclipse of agriculture even before the petroleum boom. Census and survey data indicate that the bulk of migration in Tabasco originated within the state. Most migrants travelled short distances. Unskilled were particularly likely to originate in small rural localities near the petroleum fields. Within the petroleum areas, natives and immigrants from elsewhere in Tabasco were similar in education, sex, age, and occupational status, but significant differences were noted in age, educational status, and occupational status between natives and migrants from outside Tabasco attracted by the availability of skilled employment.^ieng

"At the beginning of the seventies, important economic investments aimed at developing and commercializing the newly discovered oilwells were made in the state of Tabasco [Mexico]. As a result of this, the distribution and the social growth of the population in this state changed. This paper analyses the general characteristics of these changes, particularly those related to migration.... Generally speaking, the most important migratory movements which took place in this state during the oil boom were from one municipality to another and not from other states to Tabasco, as was thought at first.... This paper also describes the direction of the migratory flows and provides information about the sex of the migrants and about their insertion within the sphere of employment." (SUMMARY IN ENG)
