Size And Age Structure

Due to massive rural–urban migration, population size and age structure are subject to significant changes in the mountainous areas of China. This can influence the ecological pressure of the mountainous areas correspondingly. In particular, large numbers of young laborers migrate from rural areas, which may greatly decrease the intensity of local human activities. However, it is still unclear how population changes (size and age structure) affect environmental changes and how to measure these changes. We analyzed changes in the ecological footprint (EF) in the Taihang Mountain region in northern China using field survey data. From 2000 to 2016, the population size in the study area decreased by 9.7%, while the EF declined by 32.1%. The EF per capita (EF_per) decreased more rapidly with decreasing elevation, which indicated that at lower elevations, households were less dependent on local resources. For households with more elderly people, the EF_per was considerably lower than for other households in 2000. However, in 2016, this was not the case, and the households with a share of the working-age population between 50–75% had the lowest EF_per. Our study is of great practical significance for reasonably guiding population migration and rural sustainable development.

The Impact

The purpose of the study is to discuss the alternative scenarios of the demographic development of rural Russia. The Covid-19 coronavirus pandemic has changed the demographic situation in Russia: mortality and natural population decline increased, while the birth rate decreased. Ba-sed on the cohort-component method, we projected the rural population size and age structure for the period 2024-2049. Six alternative scenarios were developed: three with zero migration (without taking into account the impact of migration changes on the rural population) and three with migration. Therefore, the migration outflow coefficient was included in the three forecasting scenarios. However, the inflow of some urban population to the countryside is not ruled out. The results show that the population of rural Russia will decrease from 37.3 million (2019) to 29.6–33.1 million people (2049). The age structure of the population will change, the demogra-phic aging of rural areas will continue.

New Rural Construction

New rural construction is one of the key tasks identified by the Party and State as the national target program until 2020. Many documents of the Party and the State have been issued expressing political will to implement the tasks of building new rural areas, over 6 years of implementation, the National Target Program for new rural construction has achieved certain achievements, the appearance of rural areas of ethnic minorities and mountainous areas has gradually changed dramatically, contributing significantly to promoting socio-economic and cultural development. Many provinces and cities throughout the whole country have built some new rural models that meet nineteen criterias and arrive on time.

SummaryThis paper analyses the levels and trends of childhood mortality in urban Bangladesh, and examines whether children’s survival chances are poorer among the urban migrants and urban poor. It also examines the determinants of child survival in urban Bangladesh. Data come from the 1999–2000 Bangladesh Demographic and Health Survey. The results indicate that, although the indices of infant and child mortality are consistently better in urban areas, the urban–rural differentials in childhood mortality have diminished in recent years. The study identifies two distinct child morality regimes in urban Bangladesh: one for urban natives and one for rural–urban migrants. Under-five mortality is higher among children born to urban migrants compared with children born to life-long urban natives (102 and 62 per 1000 live births, respectively). The migrant–native mortality differentials more-or-less correspond with the differences in socioeconomic status. Like childhood mortality rates, rural–urban migrants seem to be moderately disadvantaged by economic status compared with their urban native counterparts. Within the urban areas, the child survival status is even worse among the migrant poor than among the average urban poor, especially recent migrants. This poor–non-poor differential in childhood mortality is higher in urban areas than in rural areas. The study findings indicate that rapid growth of the urban population in recent years due to rural-to-urban migration, coupled with higher risk of mortality among migrant’s children, may be considered as one of the major explanations for slower decline in under-five mortality in urban Bangladesh, thus diminishing urban–rural differentials in childhood mortality in Bangladesh. The study demonstrates that housing conditions and access to safe drinking water and hygienic toilet facilities are the most critical determinants of child survival in urban areas, even after controlling for migration status. The findings of the study may have important policy implications for urban planning, highlighting the need to target migrant groups and the urban poor within urban areas in the provision of health care services.
