The current world population is growing by about , people every day. It is projected to hit 8 billion by , 9 billion by , and 10 billion by Advances in medicine and the industrial revolution were the catalysts to the population boom.
There are fewer deaths now and babies have bigger chances of living their full lives and having children of their own. We have access to clean water and this lowered the incidence of life threating diseases like Malaria. The demands of our growing population has done much damage to our environment. But we are beginning to be more aware and take positive actions. We are taking baby steps towards the right direction. Spread the message. Make a donation.

It organizes the public into nine distinct groups, based on an analysis of their attitudes and values. Even in a polarized era, the survey reveals deep divisions in both partisan coalitions.
Pew Research Center now uses as the last birth year for Millennials in our work. President Michael Dimock explains why. The vast majority of U. Use this tool to compare the groups on some key topics and their demographics.
About Pew Research Center Pew Research Center is a nonpartisan fact tank that informs the public about the issues, attitudes and trends shaping the world. It conducts public opinion polling, demographic research, media content analysis and other empirical social science research. Pew Research Center does not take policy positions.
It is a subsidiary of The Pew Charitable Trusts. Newsletters Donate My Account. Research Topics. Education and family size The number of children a family has, as well as views of the ideal number of children, vary by educational attainment.
Their analysis of birth rates in metropolitan areas finds that all else equal, a one percentage-point increase in the unemployment rate is associated with a 1. Schaller analyzes the relationship between state-level unemployment rates and birth rates, and finds that a one percentage-point increase in state-year unemployment rates is associated with a 0.
Other evidence shows that women whose husbands lose their jobs at some point during their marriage ultimately have fewer children Lindo, This suggests that transitory changes in economic conditions lead to changes in birth rates. However, to the extent that delayed fertility results in lower total fertility for some women, then the observed reductions in current period births will reflect reductions in the total number of births.
Furthermore, if shocks to economic conditions prove to be persistent, then changes in birth rates will be as well. A deeper and longer lasting recession will then mean lower lifetime income for some people, which means that some women will not just delay births, but they will decide to have fewer children.
The COVID public health crisis has badly damaged the economy, and the recession is likely to last for many months. The Federal Reserve forecasts that the unemployment rate will still be at 9. Barrero, Bloom, and Davis predict that 42 percent of recent layoffs will be permanent. Though many of these workers will eventually find new employment, research has shown that recession-related job loss leads to persistent, large negative effects on lifetime earnings Davis and von Wachter, An analysis of the Great Recession leads us to predict that women will have many fewer babies in the short term, and for some of them, a lower total number of children over their lifetimes.
This is consistent with the evidence described above. The Great Recession led to a large decline in birth rates, after a period of relative stability. In , the birth rate was That nine percent drop meant roughly , fewer births. State-level comparisons provide a more direct link between an economic downswing and birth rates.
States in which the recession was more severe experienced greater declines in birth rates, according to our analysis of Vital Statistics birth data from the National Center for Health Statistics, population data from the U. Bureau of the Census, and state unemployment rates from the Bureau of Labor Statistics from to States in which the recession was most severe experienced larger drops in births. In this simple analysis, we find that a one percentage point increase in unemployment reduces the birth rate by 1.
That is an unweighted estimate; weighting the observations yields an estimated impact of Over a longer time period, from and , we find that that a one percentage point increase in the state unemployment rate led to a 0.
This estimate comes from a more formal econometric analysis, using a regression model estimating the natural log of the birth rate as a function of the unemployment rate in the preceding year, controlling for state and year fixed effects. A more detailed study could include other potentially relevant factors, such as expanded access to long-acting reversible contraceptives LARCS , better access to health insurance, and others. We expect however that including these factors would yield a larger estimate, since our estimated effect is on the lower end of those found in the more detailed econometric studies described above.
We have emphasized the role of weaker economic conditions in driving a future decline in births, but we hasten to acknowledge the public health aspect. The Spanish Flu provides an obvious comparison; and it generated a large decline in births. Here we show the monthly trend in the death rate due to influenza and pneumonia the main causes of death attributed to Spanish Flu , along with the aggregate birth rate births per 1, population for those states reporting Vital Statistics data at that time 21 states participated in Birth rates are backdated by nine months to approximate the month of conception:.
Large spikes in mortality were matched by large declines in births.
