“Born from parents, raised by neighbors.” This Vietnamese proverb partially reflects population movement, contributing to changes in a region’s population. So, how do we calculate the mechanical population growth rate, a crucial factor reflecting a locality’s socio-economic development? Let’s explore with HOC LAM!
What is Mechanical Population Growth Rate?
Mechanical population growth rate reflects population changes in an area due to migration. It differs from the natural population growth rate (births – deaths). Simply put, if a region is a “land of opportunity,” attracting many people to settle, the mechanical population growth rate will be positive. Conversely, if people “leave their homeland” for other places, this rate will be negative.
Formula for Calculating Mechanical Population Growth Rate
The formula is quite simple:
Mechanical Population Growth Rate (%) = [(Number of Immigrants – Number of Emigrants) / Initial Total Population] x 100
For example, at the beginning of 2023, district X had a population of 100,000 people. During 2023, 5,000 people immigrated and 2,000 people emigrated. Thus, the mechanical population growth rate of district X in 2023 is: [(5,000 – 2,000) / 100,000] x 100 = 3%.
Factors Affecting Mechanical Population Growth Rate
Many factors influence migration, from economic and social to environmental. For instance, industrial zones and major cities often attract workers, leading to a positive mechanical population growth rate. Conversely, natural disasters or epidemics can cause people to evacuate, making this rate negative. According to Assoc. Prof. Dr. Nguyen Van A, in the book “Modern Demography,” rapid urbanization is one of the main reasons for changes in mechanical population.
Significance of Calculating Mechanical Population Growth Rate
This calculation helps policymakers understand population dynamics, thereby developing appropriate socio-economic development strategies. For example, if the mechanical population growth rate is high, investment in infrastructure, education, and healthcare is necessary to meet the needs of the population.
Spirituality and Migration
The saying “auspicious land attracts birds” reflects the belief in choosing a place for peaceful settlement. Choosing a new residence is not only based on reason but also on spiritual factors, desiring to find peace and good fortune.
Frequently Asked Questions
- How is mechanical population growth rate different from natural population growth rate? Natural population growth rate only considers births and deaths, while mechanical population growth rate considers the number of people moving into and out of an area.
- How to encourage people to settle in a locality? It is necessary to create a good living environment, job opportunities, and socio-economic development.
