Populations only change because of three drivers of change: births, deaths and migration.
Dealing with statistics, forecasts and technical language can sometimes seem overwhelming. We may not use population data in our work as a result, or rely on information we feel we don’t have the expertise to make sense of it.
I’m here to assure you that with a few key insights in your toolkit, you’ll be able to take advantage of the data available to make a positive impact for the places and people you are working with. I’m often asked what’s important to look at in demography and
Populations only change because of three drivers of change: births, deaths and migration. Populations grow if there are more births, or less deaths, or more people move into an area, or less people move out. Or populations can decline when the opposite happens.
Changes to these drivers also affect the composition of a population. Retirement migration to the coast can lead to population
When looking at population we’re used to looking at how big it is, or the rate of change. But if this is the only thing we look at we’re probably missing what’s important. Everything we do is affected by age and our gender. Populations are no different. If you want to understand how a population is changing and what it needs, size only tells you so much. It’s the change in age groups that shows where that change is coming from and indicates what kind of infrastructure they will need.
By looking at both age and sex, we can make sure we are fully informed about different segments of our population. This can inform policy, highlight areas where more work is needed, as well as prompt us to ask why we’re seeing those differences.
Keep these two things in mind when talking about population or thinking about how population changes might affect the work you do for a more informed discussion about demography.
