Population predictions

Real-time population data is used to develop models and make predictions of world population growth.

Jonathan Powell


Tags Linear, Exponential, Data

The aim of this activity is to enable pupils to develop a simple model of population growth and use it to make predictions. The website www.worldometers.info provides real-time data about population, births and deaths,  and a variety of other world information. Students can extract values from the website, record them in a TI-Nspire spreadsheet and plot graphs from which mathematical models of population can be developed.

How many more people will there be by the time of the next lesson?
