Based on the provided text, outline the conditions for creating a population pyramid.

The conditions for creating a population pyramid based on the provided text are:

1. Decreasing Birth Rate: The number of children in the 0-9 age group should gradually decrease over the last 10 years.
2. Female Population Exceeding Male Population: Starting from age 65, women should be twice as numerous as men in the age groups 65-69, 70-74, and 75-79.
3. Maximum Population Age: The maximum age of the population is 80 years.
4. Demographic "Pit": There should be a noticeable decrease in the number of both males and females in the 30-40 age range, specifically in the 30-34 and 35-39 age groups.
5. Slightly More Boys Than Girls: There should be a slight excess of boys over girls in children up to 5 years old, specifically in the 0-4 age group.

Instructions for Creating the Pyramid:

1. Divide the population into 5-year age groups: 0-4, 5-9, 10-14, ..., 75-79, 80 years.
2. For each age group, determine the number of men and women, considering the conditions above.
3. Build the population pyramid with the horizontal axis representing population size (males on the left, females on the right) and the vertical axis representing age groups.
4. Pay attention to the accuracy of the presentation: axis labels, legend, title, units of measurement.

Recommendations:

• Start with a basic numerical value for each age group, then adjust it according to the conditions.
• For the demographic "pit," reduce the numbers by approximately 30-40% in the corresponding age groups.
• For older ages, increase the proportion of women relative to men by a factor of two.
• For children up to 5 years old, make the excess of boys approximately 5-10%.
