His study shows no evidence that the individual rate of aging has changed. Instead, it remains stable, suggesting that gains in life expectancy are more consistent with a later onset of senescence than with a slowing of its tempo.
Last week, we received Vegard Skirbekk, Norwegian Institute of Public Health and the University of Oslo, at UFMG. Vegard delivered two lectures focusing on population ageing and health. He also interacted with students in Demography and Public Health.

The article is here, and I'll have more to say in the coming days about how we came to this method of trying to answer, "How many Covid-19 deaths went uncounted in the US?"
A great write-up on brand-new research I was involved in. We used a really different approach from the ones that we & many others have used previously to estimate how many Covid deaths there *really* were--almost 20% more than known. Our results broadly accord w others but add new demographic detail

Hi Aida, we are working on a new version with updated results. Hopefully, we can have it out soon
Alguma novidade? A última informação apareceu no dia 27/11 informando que seriam divulgados em outra data. "O IBGE divulgará, em data oportuna a ser definida.". Não deu tempo de analisar as práticas internacionais e nem adequar a divulgação à legislação vigente?

My conclusion is that much of the worry about sub-replacement fertility is overstated. Quantitatively, the net effect of even a large fertility reduction on the US economy would be a relatively small decline in the standard of living. Comparing demographic steady states and focusing on the most easily quantified channels, a version of the United States with a total fertility rate of one child per woman would have consumption per capita that was 8.7 percent lower than a version of the country where the TFR was two. In the first four decades of the transition following a decline in fertility below the replacement rate, consumption is actually higher than it would have been if fertility had remained constant. Indeed, much of the sturm und drang regarding the economic effects of current population aging is related to the ending of such a transitory period of good times that resulted from fertility declining from its Baby-Boom highs to near replacement, starting in the 1960s. Finally, it is important to note that any attempt to fix the economic problems stemming from low fertility by raising the birth rate will entail a period of higher overall dependency in the decades that it takes the resulting children to become productive adults.
Low birth rates have modest long run negative effects, after good effects for a few decades, and raising birthrates exacerbates dependency. A giant, apparently permanent, disconnect between expert opinion (e.g., below) versus manufactured panic hype on this issue pubs.aeaweb.org/doi/pdfplus/...

fixest is an R package for fast and flexible econometric estimation, providing a comprehensive toolkit for applied researchers. The package particularly excels at fixed-effects estimation, supported by a novel fixed-point acceleration algorithm implemented in C++. This algorithm achieves rapid convergence across a broad class of data contexts and further enables estimation of complex models, including those with varying slopes, in a highly efficient manner. Beyond computational speed, fixest provides a unified syntax for a wide variety of models: ordinary least squares, instrumental variables, generalized linear models, maximum likelihood, and difference-in-differences estimators. An expressive formula interface enables multiple estimations, stepwise regressions, and variable interpolation in a single call, while users can make on-the-fly inference adjustments using a variety of built-in robust standard errors. Finally, fixest provides methods for publication-ready regression tables and coefficient plots. Benchmarks against leading alternatives in R, Python, and Julia demonstrate best-in-class performance, and the paper includes many worked examples illustrating the core functionality.

COVID-19 pandemic led to an increase in maternal mortality, with a recorded ratio of 127 deaths per 100,000 live births. Paper analyzed how the COVID-19 pandemic has influenced the magnitude and distribution of social inequalities related to maternal mortality in the Dominican Republic

This suggests that synthetic populations based on the 2010 Census should be created using the contingency tables. Our evaluation shows that the so created synthetic population maintains the values and proportions of the contingency tables and presents totals close to those of the microdata.
The data composition strategies of the contingency tables and the microdata are different and, when comparing samples of both data, we find that the race variable in the microdata ignores the presence of minorities in some municipalities.
SeconFirstly, contingency tables are available at the municipal level, for strata defined by race, gender, and education and microdata with personal information. To preserve individual anonymity, the census collapsed some variables into broader categories and removed personally identifiable data.
The 2010 Brazilian Census contains a wealth of information that could enable research and inform policies in health, education, the economy, and other sectors. The census provides publicly available information in two forms.
This is a very interesting and important paper published in the Brazilian Journal of Population Studies

In the dissertation, I analyzed the evolution and determinants of Brazilian worker retirement (1960–2000) using Censuses and Household surveys. Public pension systems are crucial for elderly well-being, making reform of the Brazilian public pension system essential.
Twenty years ago, I defended my dissertation and graduated in Demography from UC Berkeley. My advisor, Ron Lee, is in the picture with Ken Wachter, Gene Hammel, John Wilmoth, Jenna Johnson-Hanks, and Mike Hout. Event was at the old demography house - 2232 Piedmont.
