The modelling of data and prediction for the upcoming years or events
are one of the main concerns of not only all countries but also
companies, investors, manufacturers, and institutions. The scientists
investigate on a relation among telecommunication, economic growth, and
financial development using technical, economic, social events and data.
Besides, the population changes affect balances in any aspect.
Therefore, the prediction of the population for each country is
prominent and essential for the other prediction. In this study, the
dataset consists of the populations of the USA, France, Britain, Italy,
Spain, and Turkey were used from 1960 until 2018. In our study,
populations of countries are tried to be modelled, and the predictions
are made for the upcoming years, using fractional calculus. The newly
developed approach uses the data for the modelling by employing Least
Squares method and fractional calculus.
