Us population by age and sex

I use an alternative to CCRs, which I call cohort-change differences CCDs , which create linear rather than exponential growth in a blended model where county-race groups projected to grow utilize CCDs while county-race groups projected to decline utilize CCRs. I provide county-level population projections by age, sex, and race in five-year intervals for the period — for all U. That demographic data is often represented in a population pyramid. Equation 1 outlines the basic structure of a cohort-component model. The method makes use of all three population component processes fertility, mortality, and migration and applies them across varying population cohorts to arrive at a future population. One of the most common ways to illustrate that kind of demographic data is through a population pyramid , or a chart with a horizontal bar showing the number of male and female residents at each year of age. Methods The cohort-component method is the most accepted methodology to produce population projections 1 , The Hamilton-Perry method 16 , 17 is a simple, parsimonious technique for producing population projections directly from multiple age-sex distributions using cohort-change ratios CCRs 15 andis a common alternative to cohort-component. The minimal data requirements to produce CCRs and the ability to implement CCRs in Leslie matrix projection methods 18 make CCRs attractive in the production of small-area demographic projections. The lack of rigorous small-area population projections by detailed demographic subgroups has likely hampered our understanding of subnational demographic change in the United States. Despite the growing demand for subnational population projections, relatively few subnational population projections in the United States exist. Out-of-sample validation reveals errors on par with or better than cohort-component population projection models undertaken at the national and sub-national scale 18— Subject terms: My results are reasonably accurate for this period. America as a whole is getting older, and the millennial generation is coming up on its prime economic years. Two crossed lines that form an 'X'. It indicates a way to close an interaction, or dismiss a notification. Such data are useful, but lack demographic details by age, sex, or race and utilize geographies uncommon to other United States statistical reporting. Using a parsimonious cohort-component alternative 15 , I overcome the data issues associated with a typical cohort-component projection to produce a set of U. The US population pyramid clearly shows the aging baby boomer generation and the maturing millennial generation. These projections, while incredibly useful, tend to employ a variety of methods, input data, time horizons, and demographic groupings making inter-state and inter-projection comparisons difficult. The demographic pyramid for the US has consequences for the country's economic future, as the boomers continue to move into retirement and millennials enter their prime working and spending years. I validate the methods using ex-post facto evaluations using data from — to project — County-level population projections are typically only available through the gray-literature such as through the Federal and State Cooperative for Population Projections or through for-profit companies and oftentimes only comprise several states rather than the whole United States. S counties. Here's the estimated US population broken down by sex and year of age as of July 1, These projections can be used to understand small-area demographic change in the United States.

Here's the estimated US population broken down by sex and year of age as of July 1, However, CCRs suffer from two major disadvantages over the use of cohort-component: The US population pyramid clearly shows the two largest generations of Americans: America as a whole is getting older, and the millennial generation is coming up on its prime economic years. I validate the methods using ex-post facto evaluations using data from — to project — Despite the growing demand for subnational population projections, relatively few subnational population projections in the United States exist. Such data are useful, but lack demographic details by age, sex, or race and utilize geographies uncommon to other United States statistical reporting. The US population pyramid clearly shows the aging baby boomer generation and the maturing millennial generation. I then control the resultant projected age-sex structures to the five SSPs 8.

I use an alternative to CCRs, which I call cohort-change differences CCDs , which create linear rather than exponential growth in a blended model where county-race groups projected to grow utilize CCDs while county-race groups projected to decline utilize CCRs.

County-level population projections are typically only available through the gray-literature such as through the Federal and State Cooperative for Population Projections or through for-profit companies and oftentimes only comprise several states rather than the whole United States. This technique has all of the advantages of CCRs by remaining just as simple and parsimonious with minimal data requirements while producing projected populations without impossibly explosive growth. These data have numerous potential uses and can serve as inputs for addressing questions involving sub-national demographic change in the United States. One of the most common ways to illustrate that kind of demographic data is through a population pyramid , or a chart with a horizontal bar showing the number of male and female residents at each year of age.
