Question

Рассчитайте как измениться численность населения в городе если за год рождаемость составила 600 человек смертность 800 человек количество выбывших 1200 человек количество прибывших 700

Answer 1

Это отрицательная динамика численности населения . Скорее всего , в зависимости от общий численности людей, город в скором времени станет малонаселенным

Answer 2

Calculation of Population Change

To calculate the change in population in a city, we need to consider the following factors: births, deaths, and migration (both inward and outward).

Given the following information: - Births: 600 people - Deaths: 800 people - Outward migration: 1200 people - Inward migration: 700 people

We can calculate the change in population as follows:

1. Calculate the net migration by subtracting the outward migration from the inward migration: - Net migration = Inward migration - Outward migration - Net migration = 700 - 1200 = -500

2. Calculate the natural population change by subtracting the number of deaths from the number of births: - Natural population change = Births - Deaths - Natural population change = 600 - 800 = -200

3. Calculate the total population change by adding the net migration and natural population change: - Total population change = Net migration + Natural population change - Total population change = -500 + (-200) = -700

Therefore, the population of the city would decrease by 700 people over the course of the year.

Please note that this calculation assumes that there are no other factors affecting the population change, such as changes in fertility rates or life expectancy. Additionally, it's important to consider that population changes can be influenced by various social, economic, and political factors that may not be accounted for in this simple calculation.
