Abstract

Internal migration is defined as “a movement of people from one area of a country (especially one local government area) to another area of the same country for the purpose or with the effect of establishing a new residence” either temporarily or permanently, is a complex and multidimensional process. In this study we are expected to determine the impact of internal migration in Port Harcourt city and Bori town respectively and to show the effect of the variation of some parameters that affect the growth of Port Harcourt city, through Simplified Assumptions and Mathematical Formulations. The internal migration of effective working population from Port Harcourt city to Bori town is lesser than that of Bori town to Port Harcourt city due to lesser jobs and social infrastructural facilities in Bori than Port Harcourt. Method of Analysis used is a non-linear ordinary differential equation of order 45 which otherwise is called O.D.E 45(Matlab ODE 45). It is evident from the results of the study that the variation of the rate of internal migration can produce either a positive or a negative effect on the population growth patterns of the two interacting population predictions.

Highlights

Internal migration is defined as “a movement of people from one area of a country to another area of the same country for the purpose or with the effect of establishing a new residence” (IOM, 2011 as recommended in ACP Observatory Research Guide, 2011a) either temporarily or permanently, is a complex and multidimensional process
The migration will enhance the population of Port Harcourt city. 2.1 Simplifying Assumptions The mutualistic interaction between a bigger city called Port Harcourt city council and a relatively smaller city called Bori town can be understood by considering the following simplifying assumptions: i The internal migration of the effective working population of Bori town tends to enhance the growth of Port Harcourt city, where as the internal migration of the Port Harcourt city working population tends to enhance the growth of Bori town
The findings from the results showed that if growth rate and intra-competition coefficient due to internal migration of Port Harcourt city are fixed and the rate of internal migration varies, it impacts on the population of Port Harcourt

Summary

Introduction

Internal migration is defined as “a movement of people from one area of a country (especially one local government area) to another area of the same country for the purpose or with the effect of establishing a new residence” (IOM, 2011 as recommended in ACP Observatory Research Guide, 2011a) either temporarily or permanently, is a complex and multidimensional process. Internal migration has been an issue in the city of Port Harcourt, following the fact that it is the only well developed and industrialized city in Rivers state This has brought about continuous movement of people to the city to seek for better jobs, schools and modern social amenities that are not available in their localities. There is increasing demand for jobs and social amenities, overstretching available facilities It is this impacting factors that have prompted this research work, but for this work we are considering the impact of internal migration on the growth of Port Harcourt city and how sensitive the population is to the parameter values of population that changes over time.
