Aging in Mexico: Population Trends and Emerging Issues.

ABSTRACT: Although all nations in the America's face a common demographic reality of longevity, declining fertility rates and changes in family roles a growing body of research points to a dramatic demographic transformation in Mexico. Although Mexico's population is relatively young, with a median age of 27.9 in 2015, it will age rapidly in coming years, increasing to 42 years by 2050. The rapid median age in the nation also reflects the growing proportion of people 65 or older, and is expected to triple to 20.2% by 2050. This article examines how the age and gender structure of Mexico offers important insights about current and future political and social stability, as well as economic development. Mexico is the world's eleventh largest country in terms of population size and the "demographic dividend" of a large youthful population is giving way to a growing older population that will inevitably place demands on health care and social security. The shift in age structure will result in increased dependency of retirees on the working-age population in the next 20 years. Mexico does not provide universal coverage of social security benefits and less than half of the labor force is covered by any pension or retirement plan. As a result, elderly Mexicans often continue working into old age. The high total poverty rate in the country, especially among the older population magnifies the problem of the potential dependency burden. The article ends with a discussion of key public policy issues related to aging in Mexico.

Project description:The jaguar (Panthera onca) is one of the most threatened carnivores in the Americas. Despite a long history of research on this charismatic species, to date there have been few systematic efforts to assess its population size and status in most countries across its distribution range. We present here the results of the two National Jaguar Surveys for Mexico, the first national censuses in any country within the species distribution. We estimated jaguar densities from field data collected at 13 localities in 2008-2010 (2010 hereafter) and 11 localities in 2016-2018 (2018 hereafter). We used the 2010 census results as the basis to develop a National Jaguar Conservation Strategy that identified critical issues for jaguar conservation in Mexico. We worked with the Mexican government to implement the conservation strategy and then evaluated its effectivity. To compare the 2010 and 2018 results, we estimated the amount of jaguar-suitable habitat in the entire country based on an ecological niche model for both periods. Suitable jaguar habitat covered ~267,063 km2 (13.9% of the country's territory) in 2010 and ~ 288,890 km2 (~14.8% of the country's territory) in 2018. Using the most conservative density values for each priority region, we estimated jaguar densities for both the high and low suitable habitats. The total jaguar population was estimated in ~4,000 individuals for 2010 census and ~4,800 for the 2018 census. The Yucatan Peninsula was the region with the largest population, around 2000 jaguars, in both censuses. Our promising results indicate that the actions we proposed in the National Jaguar Conservation Strategy, some of which have been implemented working together with the Federal Government, other NGO's, and land owners, are improving jaguar conservation in Mexico. The continuation of surveys and monitoring programs of the jaguar populations in Mexico will provide accurate information to design and implement effective, science-based conservation measures to try to ensure that robust jaguar populations remain a permanent fixture of Mexico's natural heritage.
