The unauthorized Mexican immigrant population and welfare in Los Angeles County: a comparative statistical analysis.

"Using a unique 1994 Los Angeles County Household Survey of foreign-born Mexicans and the March 1994 and 1995 Current Population Surveys, we estimate the number of unauthorized Mexican immigrants (UMIs) residing in Los Angeles County, and compare their use of seven welfare programs with that of other non-U.S. citizens and U.S. citizens. Non-U.S. citizens were found to be no more likely than U.S. citizens to have used welfare, and UMIs were 11% (14%) less likely than other non-citizens (U.S.-born citizens).... We demonstrate how results differ depending on the unit of analysis employed, and on which programs constitute ¿welfare'."

Unauthorized Mexican workers in the 1990 Los Angeles County labour force.

"By analysing how unauthorized Mexicans compare with seven other ethno-racial groups in Los Angeles County, separately and collectively, by educational attainment and time spent in the U.S., we find that unauthorized Mexicans had relatively fewer years of formal education (either in the U.S. or in Mexico) and had been in the U.S. a relatively fewer number of years than in-migrants of other ethno-racial backgrounds in 1990. These findings are then used as proxies to compare the human capital endowments of different ethno-racial groups. We next estimate the number of unauthorized Mexicans by occupation, industry and class of worker, and compare these distributions with the total labour force and with the other ethno-racial groups in Los Angeles County.... Results show that amounts of human capital are positively related to the kinds of occupations filled." (SUMMARY IN FRE AND SPA)

Migration from Latin American countries to the United States: the economic, social and reproductive lives of Hispanic female immigrants, 1980.

The authors describe the socioeconomic characteristics and fertility patterns of female immigrants from Latin America to the United States, with a focus on reasons for fertility differentials. "Using the one per cent public use sample from the 1970 and 1980 United States census, we first compare changes in socio economic characteristics from 1970 to 1980, and then examine the determinants of fertility of female immigrants to the United States, aged 16-49, from four Latin American areas or countries of birth.... The findings...suggest that there are direct effects of demographic, assimilation, and socioeconomic variables beyond those mediated by the variables in each of these sets. Further, regardless of the model, the effect of the clusters of demographic characteristics is most apparent. Age categories and marital status are the strongest indexed determinants of immigrant fertility.... The effect of education and employment is strong. Among assimilation variables, duration of residence and language ability are significant determinants of Hispanic immigrant fertility." (SUMMARY IN FRE AND SPA)

Variations in fertility and earning patterns among immigrants in the United States, 1970-1980: assimilation or disruption?

"This paper examines the assimilation of immigrants in familial and economic fields.... Specific objectives are as follows: (1) to describe fertility and earning patterns among immigrants to the United States in 1970-1980, from several countries of origin, and (2) to describe some effects of assimilation, human capital, and the dual labor market perspectives on immigrant earnings." Findings vary in both fertility and economic categories for migrants depending on whether they are from developed or developing countries. (SUMMARY IN FRE AND SPA)

What is the annual net flow of undocumented Mexican immigrants to the United States?

Senior government officials have claimed that in recent years an average of 1.4 million illegal aliens have entered the United States annually without apprehension. This conjectural figure does not take into account the fact that the net flow of immigrants is always less than the gross flow. In this paper, seven estimates are made concerning the net flow of undocumented Mexican immigrants to the United States in the period 1970--1975. These estimates are based on the growth of the population of Mexican origin according to the Current Population Survey. According to these estimates the annual net flow ranged from 82,300 to 232,400 persons.

Does choice make a difference to contraceptive use? Evidence from east Java.

This study investigates sustained use of contraceptives among women in East Java, Indonesia. Interest is focused on the effect of whether the client's choice of contraceptive method was granted or denied, and the interaction between whether choice was granted or denied and husband-wife concurrence concerning method choice. Data were collected twice in a panel survey. The first round was conducted in family planning clinics among women initiating contraceptive use; the second was a follow-up household survey carried out 12 months later. Whether the user was granted her choice of method was found to be a very important determinant of sustained use of contraceptives. The interaction between whether choice was granted and whether there was husband-wife concurrence on method choice was also important. The highest rate of discontinuation occurred when method choice was denied in the presence of husband-wife agreement on method choice, and the lowest rate occurred when method choice was granted in the presence of such concurrence. The results imply that contraceptive continuation can be enhanced either when family planning workers pay more attention to the stated desires of their clients, or when policy is instituted allowing clients to use their method of choice.
