The first period is treated as the training sample and the latter two the testing subperiods. The mortality surface method delivers the most accurate forecasts of the mortality profiles whereas using the district-level standardized mortality rates (SMR) calculated for several broad age groups to scale the country-level mortality forecasts gives the best life expectancy at birth predictions. The latter approach is far better than using the NUTS-2-based standardized mortality rate (SMR), as practiced by the Polish statistical agency. For single age-groups predictions, the SMR-based methods deliver relatively accurate forecasts for young cohorts, but their forecasting accuracy deteriorates significantly with age.</p>","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"1 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139062240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We calculated adjusted age-specific birth registration completeness by converting period age-specific completeness data into a hypothetical cohort. Timing of birth registration was analysed using ratios of adjusted age-specific completeness, with differentials by region, over time, and level of completeness assessed using bivariate and multivariate analyses. Almost 20% of registered births in countries with incomplete birth registration (less than 95%) were not registered until after 12 months, and this has not improved since 2010. In several countries this figure is greater than 50%, particularly in South Asia. There remains considerable scope to improve the timeliness of birth registration, particularly in countries where the overall level of completeness is lower. Strengthening and enforcing legislation for the mandatory registration of births before age 12 months and greater involvement of the health sector in registration processes are two ways which will improve birth registration timing.</p>","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"10 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the datasets of the Australian Bureau of Statistics, this study presents an in-depth investigation of the healthy migrant effect and its age variations in Australia. Specifically, this study estimates life expectancy (LE) and healthy life expectancy (HLE) of the Australia-born and overseas-born populations, as well as eight Australian migrant groups, and decomposes the HLE differences into mortality and morbidity differences from three dimensions: age, gender and country of birth. The results reveal that compared with the Australia-born population, the overseas-born population enjoys a prominently longer LE; however, they suffer a similar or lower HLE after age 65 and a lower HLE/LE ratio throughout all ages. Young overseas-born adults manifest a more significant health advantage in both mortality and morbidity than early-life and older overseas-born individuals; however, the morbidity advantage of young migrants, particularly those who are female and originated from culturally different countries, declines dramatically with ageing. The results suggest that overall, migrants do not have the same advantage in morbidity as they do in mortality and that health advantages of migrants decreases with time in both dimensions of health and more rapidly for morbidity. The results suggest that pertinent policies are needed to reduce acculturation-related challenges and to mitigate the decline in migrants’ health in the post-migration environment to ensure better quality of life outcomes of migrants.</p>","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"73 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mortality risk by cohorts may differ at a regional level, given that health inequalities (and the determinants of smoking and its consequences) are regionally patterned. We applied an Age-Period-Cohort model to identify birth cohort effects on female lung cancer mortality in Spain. We found a strong linear increase in lung cancer mortality during the 1980–2019 period in all regions. Cohorts born between 1935 and 1955 presented a higher relative risk of death at a national and subnational level. However, we found diverging cohort patterns across regions afterward, with some regions presenting a slight mortality improvement (or stagnation) in their youngest cohorts, while in other regions mortality kept increasing. This suggests that inequalities in lung cancer mortality in Spain among women are not only generationally based, but that generational risks also vary across space. Some of the regions that presented improvements in mortality among its younger cohorts are Madrid, Navarra, and the Basque Country, which are some of the wealthiest in the Country. While speculative, this could imply that improvements at a regional level might be associated with factors related to structural conditions that result in the adoption of healthy behaviors.</p>","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"48 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review uncovers the underlying determinants associated with changes in fertility and their relationship with disasters. This review examines peer-reviewed journal articles published between 1990 and 2022, which focused on disaster events regardless of time and place, written in English and available with full-texts, including those categorized under <i>Demography, Family Studies, Environmental Studies</i> and <i>Geography</i> in selected databases: Web of Science, Scopus, CINAHL, PubMed, and Google Scholar. In total, 73 original articles were analyzed. Disasters have varying effects on fertility rates, with some studies showing an increase in fertility due to limited access to reproductive health services and the impact of child mortality. In contrast, others indicate a decline linked to socioeconomic changes and restricted healthcare access. Policymakers and researchers must consider these complexities when designing interventions to address the diverse impacts of disasters on fertility patterns and behaviors.

Not only have Indigenous peoples thwarted colonial tropes of the vanishing native but, for decades, Indigenous population growth rates have significantly outpaced those of the dominant settler populations. The future survival of Indigenous peoples fundamentally rests on continued natural increase, and understanding the causes and consequences of fertility behaviour is critical. While total fertility rates for Indigenous women in CANZUS countries are relatively low, childbearing tends to be concentrated at younger ages in contrast to the dominant white populations. The fertility transitions of both settler and Indigenous populations in the CANZUS states are well documented, however, a significant gap remains: how cultural factors shape contemporary Indigenous fertility behaviours. Using Aotearoa as a case study, we explore the relationship between Māori cultural identity, birth timing, and the duration of birth intervals. We use the 1995 New Zealand Women: Family, Employment and Education survey data to further test the impact of cultural identity on birth transition rates using the piecewise exponential model and Kaplan-Meier estimates. We find that women who identify Mainly Māori (exclusively or primarily) are at greater risk of bearing much earlier to first birth but not necessarily subsequent births. However, because of the earlier start, Māori have a longer reproductive window to bear more children, and at higher birth orders still bear earlier than non-Māori. The empirical evidence strengthens our case to suggest that cultural orientation has some influence on Indigenous fertility and contributes to the development of Indigenous-centred theories of fertility and demography more broadly.","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"52 7-8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136381748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expected LOS was estimated via the hazard function of exiting from such a facility and its heterogeneity by residents’ sociodemographic characteristics using an improved Cox regression model. Data were sourced from the Australian Institute of Health and Welfare. In-sample modelling results reveal that the estimated LOS differed by age (in general, shorter for older groups), marital status (longer for the widowed) and sex (longer for females). In addition, the estimated LOS increased slowly from 2008–2009 to 2016–2017 but declined steadily thereafter. Out-of-sample predictions suggest that the declining trend of the estimated LOS will continue until 2040 and that the longest LOS (approximately 37 months) will be observed among widowed females aged 50–79 years. Relative uncertainty measures are provided. The results portray the current changing landscape and the future trend of residential aged care use in Australia, which can inform the development of optimised residential aged care policies to support ageing Australians more effectively.","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134887149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some 8514 women and 3618 men were asked about the ideal composition of their family. Results show major differences between women and men: women were more often indifferent (11.9% vs. 9.9%), equalitarian, i.e. preferring the same number of boys and girls (53.1% vs. 43.1%) or preferring more girls (16.7% vs. 8.4%) than men, while men were more likely to prefer more boys (37.6% vs. 18.3%). The relative preference for girls was therefore 4.1 larger for women than for men. Several socio-economic factors were investigated: urban residence, level of education, household wealth, and exposure to media, but had hardly any impact on sex-preferences. In contrast, cultural and ethnic factors were strong. White/European groups had higher preference for boys, while Black/African groups showed virtually no differential preference between boys and girls, like in nearby southern African countries. Some minor differences could be noted among ethnic groups, in particular among Zulus and Xhosas. At ethnic level, nuptiality, in particular polygyny, and household structure showed a correlation with sex-preferences. Lastly, current family composition had an effect on stated preferences, showing that on average men and women were rather satisfied with the sex-composition of their family.","PeriodicalId":45624,"journal":{"name":"JOURNAL OF POPULATION RESEARCH","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136061277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
