China’s Population to Peak at 1.4 Billion Around 2026. Census Bureau Projects India to Become Most Populous Country in 2025.
Source: U.S. Census Bureau
From Press Release:
China’s population is projected to peak at slightly less than 1.4 billion in 2026, both earlier and at a lower level than previously projected. Meanwhile, India’s population is projected to surpass China’s population in 2025, according to new data being released by the U.S. Census Bureau.
The Census Bureau’s International Data Base includes projections by sex and age to 100-plus for 227 countries and other areas with populations of 5,000 or more and provides information on population size and growth, mortality, fertility and net migration.
These figures come from the population estimates and projections for 227 countries and areas released today through the Census Bureau’s International Data Base. This release includes revisions for 21 countries, including China.
The latest projections indicate that by 2026, the population of China will begin to decline. Population growth in China, the world’s most populous country, is slowing and currently stands at 0.5 percent annually. China surpassed the 1.2 billion population mark in 1994 and reached 1.3 billion in 2006.
According to the latest revisions, India is projected to become the world’s most populous country in 2025. The population growth rate in India currently is about 1.4 percent, nearly three times that of China. The difference in the growth rate between the two countries is explained by fertility. India’s total fertility rate — the number of births a woman is expected to have in her lifetime — is currently estimated at 2.7 and projected to decline slowly, and that is driving population growth in the country.

* In 2007, the age-adjusted death rate for the United States reached a record low of 760.3 per 100,000 population. Life expectancy at birth reached a record high of 77.9 years.
* States in the southeast region have higher death rates than those in other regions of the country.
* In 2007, the five leading causes of death were heart disease, cancer, stroke, chronic lower respiratory diseases, and accidents. These accounted for over 64 percent of all deaths in the United States.
* White females have the longest life expectancy (80.7 years), followed by black females (77.0 years).
* The gap in life expectancy between white persons and black persons declined by 35 percent between 1989 and 2007. The race differential was 4.6 years in 2007.

Supplemental U.S. Population Projections: 2000-2050

The Census Bureau will release a set of four national projections supplementing the series released in August 2008, showing projections to 2050 by age, race, sex and Hispanic origin. These four scenarios assume either high, low, constant or zero international migration between 2000 and 2050. The August 2008 projections remain the preferred series for users.

Children born to low-income parents with savings above the median level are more likely to move up the income ladder as adults (71 percent do) than those whose parents are low-income and low-saving (only 50 percent move up from the bottom rung), according to a new report released today by Pew’s Economic Mobility Project. A Penny Saved is Mobility Earned: Advancing Economic Mobility through Savings similarly shows that within an individual’s lifetime, savings increases one’s chances of being upwardly mobile – 34 percent of the adults who had low-savings and were in the bottom income quartile from 1984-1989 had moved up from the bottom by 2003-2005, whereas 55 percent of those who had high-savings moved up by the same time period.

Using State Tests in Education Experiments: A Discussion of the Issues

Securing data on students’ academic achievement is typically one of the most important and costly aspects of conducting education experiments. As state assessment programs have become practically universal and more uniform in terms of grades and subjects tested, the relative appeal of using state tests as a source of study outcome measures has grown. However, the variation in state assessments—in both content and proficiency standards—complicates decisions about whether a particular state test is suitable for research purposes and poses difficulties when planning to combine results across multiple states or grades. This discussion paper aims to help researchers evaluate and make decisions about whether and how to use state test data in education experiments. It outlines the issues that researchers should consider, including how to evaluate the validity and reliability of state tests relative to study purposes; factors influencing the feasibility of collecting state test data; how to analyze state test scores; and whether to combine results based on different tests. It also highlights best practices to help inform ongoing and future experimental studies. Many of the issues discussed are also relevant for non-experimental studies.
