ECONOMIC OPPORTUNITY IN MEXICO AND RETURN MIGRATION FROM THE UNITED STATES

I analyze the influence of the economic characteristics of origin area on trip duration for Mexican migrants in the United States. I argue that migrants from economically dynamic areas in Mexico with favorable opportunities for employment and small capital investment have a larger incentive to stay in the United States longer and to withstand the psychic costs of separation from family and friends than do migrants from economically stagnant areas in Mexico, where the productive uses of savings are severely limited. In line with this argument we should expect investment opportunities in migrants’ origin areas to be associated positively with migrants’ trip duration in the United States. To test this hypothesis I use individual- and household-level data on U.S migration experience collected in 13 Mexican communities. Evidence from parametric hazards models supports the idea that economic characteristics of origin areas influence the motivations and strategies of Mexican migrants in the United States.

The impact of war, famine, and economic decline on marital fertility in ethiopia

We examine recent fertility trends in Ethiopia for evidence of short- and long-term responses to famine, political events, and economic decline. We use retrospective data on children ever born from the 1990 National Family and Fertility Survey to estimate trends in annual marital conception probabilities, controlling for women’s demographic and socioeconomic characteristics. The results of our analysis provide evidence of significant short-term declines in conception probabilities during years of famine and major political and economic upheaval. In the longer term, marital fertility in both urban and rural areas declined in the 1980s after increasing moderately in the 1970s.

The Short- and Long-Term Effects of U.S. Migration Experience on Mexican Women's Fertility

Using retrospective fertility and migration histories from a binational study of Mexico-U.S. migration, we test for the presence of separation, assimilation, adaptation, diffusion, and selectivity effects of migration on annual birth probabilities and completed fertility. Our results reveal that spousal separation due to temporary migration reduces birth probabilities in the short term but does not reduce marital fertility in the long term. However, when women migrate to the U.S. either as temporary migrants or as long-term settled migrants, their experiences lead to lower birth probabilities while in the U.S. as well as to fewer total births. By contrast, U.S. migration experience among men who return to Mexico is associated with higher marital fertility in Mexico, suggesting that temporary migrants are selected for higher fertility.

Local economic opportunity and the competing risks of internal and U.S. migration in Zacatecas Mexico.

This article uses a competing risks model to examine the effects of origin economic conditions on the probability of temporary U.S. and internal labor migration in the Mexican state of Zacatecas. We measure origin economic conditions with municipal-level indices of employment and small-scale investment opportunities that we constructed from population and economic census data. The results of our analysis demonstrate the important influence of local employment and investment opportunities on migration outcomes. Controlling for the prior municipal rate of U.S. return migration and other factors, positive opportunities for small-scale investment are associated with a higher risk of temporary migration to the United States. This result is consistent with investment oriented migration predicted by the new economics of labor migration theory. We also find comparable social network effects for both internal and U.S. migration. Having social ties to active migrants of one type (U.S. or internal), encourages migration of the same type and discourages migration of the other type.

Food insecurity, school absenteeism and educational attainment of adolescents in Jimma Zone Southwest Ethiopia: a longitudinal study

BackgroundFood insecurity not only affects physical growth and health of children but also their intellectual development, school attendance and academic performance. However, most evidences are based on studies in high income countries. Although food insecurity is common in Ethiopia, to what extent it affects school attendance and educational attainment of adolescents is not explored. We hypothesized that food insecure adolescents would be more likely to be absent from school and have lower grades attained after 1 year compared to their food secure peers.MethodsWe used data from 2009 adolescents in the age group of 13-17 years from two consecutive surveys of a five year longitudinal family study in Southwest Ethiopia. A stratified random sampling was used to select participants. Regression analyses were used to compare school absenteeism and the highest grade attained after 1 year of follow-up in food secure and insecure adolescents. The analysis was adjusted for demographic factors, reported illness and workload.ResultsSignificantly more (33.0%) food insecure adolescents were absent from school compared with their food secure peers (17.8%, P < 0.001). Multivariable logistic regression analyses showed that after adjusting for gender, place of residence and gender of the household head, adolescent food insecurity [OR 1.77 (1.34-2.33)], severe household food insecurity [OR 1.62 (1.27-2.06)], illness during the past one month before the survey [OR 2.26 (1.68-3.06)], the highest grade aspired to be completed by the adolescent [OR 0.92 (0.88-0.96)], and the number of days that the adolescent had to work per week [OR 1.16 (1.07-1.26)] were independent predictors of school absenteeism. Similarly after controlling for household income and gender of the household head, adolescent food insecurity(P < 0.001), severe household food insecurity(P < 0.001), illness during the last month(P < 0.001) and rural residence(P < 0.001) were inversely associated with highest grade attained, while age of the adolescent(P < 0.001), the highest grade intended to be completed(P < 0.001) and residence in semi urban area(P < 0.001) were positively associated with the highest grade attained.ConclusionsAdolescent and household food insecurity are positively associated with school absenteeism and a lower educational attainment. Programs aiming to achieve universal access to primary education in food insecure environments should integrate interventions to ensure food security of adolescents.

Pioneers and Followers: Migrant Selectivity and the Development of U.S. Migration Streams in Latin America

The authors present a method for dividing the historical development of community migration streams into an initial period and a subsequent takeoff stage with the purpose of systemically differentiating pioneer migrants from follower migrants. The analysis is organized around five basic research questions. First, can we empirically identify a juncture point in the historical development of community-based migration that marks the transition from an initial stage of low levels of migration and gradual growth into a takeoff stage in which the prevalence of migration grows at a more accelerated rate? Second, does this juncture point exist at roughly similar migration prevalence levels across communities? Third, are first-time migrants in the initial stage (pioneers) different from first-time migrants in the takeoff stage (followers)? Fourth, what is the nature of this migrant selectivity? Finally, does the nature and degree of pioneer selectivity vary across country migration streams?

Gender Differences in Food Insecurity and Morbidity Among Adolescents in Southwest Ethiopia

OBJECTIVE: Several studies have shown the adverse health consequences of food insecurity on household members. To what extent this relationship is mediated by gender among adolescents has not been documented. We hypothesized that the health consequences of food insecurity would be more pronounced in girls compared with boys. METHODS: We used the first-round data from a 5-year longitudinal family survey of 2084 adolescents aged 13 to 17 years from urban, semiurban, and rural areas of southwest Ethiopia. Stratified random sampling was used to select households and adolescents. Multivariable logistic regression was used to compare self-reported morbidity according to food-security status and gender after adjusting for nutritional and socioeconomic covariates. RESULTS: Overall, 29.9% of girls and 19.2% of boys reported illness during the previous 1 month before the survey. Food-insecure girls were twice as likely to report suffering from an illness (P < .01) compared with boys, and the risk of reported illness tripled when girls were food insecure and were part of food-insecure households (P < .01). Girls were 7.4 and 7.0 times more likely to report difficulties with activities because of poor health and having a feeling of tiredness/low energy compared with boys, respectively (P < .001). CONCLUSIONS: We report that in a food-insecure situation, gender is an important predictor of an adolescents self-reported health status. Food-security interventions should consider gender as a key variable to narrow the gap in health between boys and girls.

Household capacities, vulnerabilities and food insecurity: Shifts in food insecurity in urban and rural Ethiopia during the 2008 food crisis

The global food crisis of 2008 led to renewed interest in global food insecurity and how macro-level food prices impact household and individual level wellbeing. There is debate over the extent to which food price increases in 2008 eroded food security, the extent to which this effect was distributed across rural and urban locales, and the extent to which rural farmers might have benefited. Ethiopias food prices increased particularly dramatically between 2005 and 2008 and here we ask whether there was a concomitant increase in household food insecurity, whether this decline was distributed equally across rural, urban, and semi-urban locales, and to what extent pre-crisis household capacities and vulnerabilities impacted 2008 household food insecurity levels. Data are drawn from a random sample of 2610 households in Southwest Ethiopia surveyed 2005/6 and again in mid to late 2008. Results show broad deterioration of household food insecurity relative to baseline but declines were most pronounced in the rural areas. Wealthier households and those that were relatively more food secure in 2005/6 tended to be more food secure in 2008, net of other factors, and these effects were most pronounced in urban areas. External shocks, such as a job loss or loss of crops, experienced by households were also associated with worse food insecurity in 2008 but few other household variables were associated with 2008 food insecurity. Our results also showed that rural farmers tended to produce small amounts for sale on markets, and thus were not able to enjoy the potential benefits that come from greater crop prices. We conclude that poverty, and not urban/rural difference, is the important variable for understanding the risk of food insecurity during a food crisis and that many rural farmers are too poor to take advantage of rapid rises in food prices.

Ethiopian adolescents' attitudes and expectations deviate from current infant and young child feeding recommendations.

PURPOSE Suboptimal infant and child feeding practices are highly prevalent in many developing countries for reasons that are not entirely understood. Taking an anthropological perspective, we assessed whether nulliparous youth have formulated attitudes and expectations in the domain of infant and child feeding behaviors, the extent to which these varied by location and gender, and the extent to which they deviated from current international recommendations. METHODS A population-based sample of 2077 adolescent girls and boys (13-17 years) in southwest Ethiopia answered a questionnaire on infant and young child feeding behaviors. RESULTS Results indicate high levels of agreement among adolescents on items relating to infant and young child feeding behaviors. Attitudes and intentions deviated widely from current international recommendations. Youth overwhelmingly endorsed items related to early introduction of nonbreast milk liquids and foods. For girls, fewer than 11% agreed that a 5-month infant should be exclusively breastfed and only 26% agreed that a 6-month infant should be consuming some animal source foods. Few sex differences emerged and youth responses matched larger community patterns. CONCLUSIONS The results indicate that attitudes and expectations deviate widely from current international child feeding guidelines among soon to be parents. To the extent that youth models are directive, these findings suggest that youth enter into parenthood with suboptimal information about infant and child feeding. Such information will reproduce poor health across generations as the largest cohort of adolescents ever become parents. These results suggest specific points of entry for adolescent nutrition education interventions.

Rural-urban migration and reproductive behavior in Guatemala.

Guatemala has the highest fertility of any country in Latin America, and it is also the least urbanized. Projected rural-urban migration will shift more of Guatemalas population from rural areas into towns and cities. This article uses retrospective life-history data collected in migrant origin and destination areas in Guatemala to compare the fertility of rural-urban migrant women to that of rural and urban nonmigrants. Results from discrete-time hazard regression models of union formation, first birth, and third and higher parity births indicate that delayed marriage while still in rural areas, and the rapid adoption of urban fertility practices after migration, result in intermediate migrant fertility that is closer to that of urban natives than rural nonmigrants. If current patterns are any guide to the future, the redistribution of population from high fertility rural areas to towns and cities in Guatemala will accelerate the decline in aggregate fertility beyond what would have resulted from declines in rural and urban fertility alone.
