The Birth of the Earth's 6 Billionth Inhabitant

world population growth rate

Currently, about 259 people are born every minute in the world, 15,540 people are born every hour, and about 370,000 people are born every day, with an annual increase of about 82.96 million people. About 38 people are born every minute in our country (one person is born in less than 2 seconds on average), about 22.37 million people are born every hour, and about 50,000 people are born every day.

Based on the animation "World Population Growth" animation, summarize the characteristics of population growth.

Tip: The law of world population growth is: from 1830 to 1999, the time required for the world's population to grow by one billion gradually became (shorter), which shows that during this period, the world's population growth rate gradually became (faster).

The rate of population growth is determined by birth and death rates.

Natural population growth rate = population birth rate – population death rate. The natural growth rate is greater than 0, which means the population is increasing.

Calculate the birth rate, death rate and natural growth rate of the population in 2003 for the four countries in the table below.

(1) Rank these countries according to their natural population growth rate and see which country has the largest natural population growth rate?

In descending order of natural population growth rate, they are: Nigeria, Brazil, England, and Italy. Nigeria has the largest population growth rate.

(2) How is the natural population growth rate of Italy different from that of the other 3 countries, and what does this mean?

Italy's natural population growth rate is less than 0, indicating that Italy has experienced negative population growth, which means that Italy's population is constantly decreasing.

3. Population Issues

1. Problems caused by rapid population growth

Problems caused by population growth and solutions

Countermeasures to be taken to address current population problems

Control the population size and improve the quality of the population;

Population growth must be compatible with social and economic development and coordinated with the environment and resources.

The main reasons for rural population migration to cities:

A. Rural population growth creates a surplus of labor.

B. Differences between urban and rural areas - there are relatively more employment opportunities in cities, the material living conditions in cities are good, and the cultural and educational conditions in cities are better than those in rural areas.

The impact of the influx of rural people into cities on urban development:

(1) Increase the city’s labor source;

(2) Increase the city’s purchasing power of goods;

(3) Bringing pressure on the city in terms of housing, transportation, etc.;

(4) Impact on urban management.

Consolidate training

1. On average, for every 20,000 people in a certain area, 80 people were born and survived that year, and 46 people died. The birth rate, death rate, and natural growth rate of the population in this area in a year are ( )

A.4‰ 2.3‰ 1.7‰ B. 4‰ 4.6‰ 0.4‰

2. Read the picture and complete the following questions.

(1) The picture vividly explains the concept of _______________.

(2) The left side of the scale represents the _______ population. The right side of the scale represents _________ population.
