World population by age range
List of Tables - Home - Swansea Bay University Health Board
In the ABMU LHB area as whole the bulk of the population is aged between 25 – 64 years (51 per cent), this age range accounts for 52.0% of the population in Neath Port Talbot. Of the three local authorities Neath Port Talbot has the highest proportion of its population aged 65 years and over (20.6 per cent).
AGE PYRAMID ACTIVITY
The age-dependency ratio is often used as an indicator of economic burden the productive portion of a population must carry – even though some persons defined as “dependent” are producers, and some persons in the “productive” age range are economically dependent.

The top figure shows the population-age pyramid for the developed world and the bottom figure is for the developing world. The figure illustrates the pyramids for the years 1975 (pink) and 2000 (blue). The population/age structure of the developed world represents that of a stable (or nearly stable) population.

The population ending in each digit over a given range, say 23 to 82, or 10 to 89, may be compared with one-tenth of the total population in the range, as was done for digit “0” earlier, or it may be expressed as a percentage of the total population in the range.

An age pyramid with more long bars for the younger age groups would indicate a growing population; when these large numbers of young begin to reproduce, they will add even more offspring to the population than did the older age groups. For great population pyramids you should visit www.census.gov, and navigate to the international section ...

An example of two such population-age pyramids is shown in Figure 3. Figure 3: Population/Age Pyramids of the Developed and Developing World . The top figure shows the population-age pyramid for the developed world and the bottom figure is for the developing world. The figure illustrates the pyramids for the years 1975 and 2000.

Were the age distribution to change in a very irregular fashion over the age range, for instance, much information would be lost by a single-index summary. Therefore, perhaps the most adequate approach to study population aging is to explore the age distribution through a set of percentiles, or graphically by analyzing the population pyramids.

This does not tell us age distributions, or what ages most deaths occur. You don’t need to memorize this, but it is nice to know how to calculate this basic information. Natural increase rate (NIR) = ( CBR – CDR) /10 (equation 1) Doubling time in years = log(2) / log(1+NIR) (equation 2) Figure 1: NIR and population growth.

Because of an ageing population (people living longer, delaying when they have children, reducing the number of children they have, and reduced infant mortality) the world in the mid-range future – 50 years – and certainly the longer term future – 100 years plus – will likely look quite dramatically different.

IIASA used baseline data on population size, total fertility rates, and life expectancies from the Population Reference Bureau's 1995 World Population Data Sheet (see PRB, 2000 for the most recent version), combined with age distributions of population and vital rates from the UN 1994 Revision (Lutz et al., 1996b).
