To determine which country Russia compares most closely to, we'll analyze the given data for Russia and compare it with the data for each of the other countries: Brazil, Mexico, Japan, and Uganda.
### Step 1: Analyzing the Data
For Russia, the provided data is:
- Population growth rate: -0.02%
- Fertility rate: 1.61
- Life expectancy: 70 years
### Step 2: Given Data for Comparison
For Brazil from the table, the data is:
- Population growth rate: 0.83%
- Fertility rate: 1.81
- Life expectancy: 73 years
For Mexico (hypothetical values), the data is assumed to be:
- Population growth rate: 1.24%
- Fertility rate: 2.20
- Life expectancy: 76 years
For Japan (hypothetical values), the data is assumed to be:
- Population growth rate: -0.14%
- Fertility rate: 1.38
- Life expectancy: 84 years
For Uganda (hypothetical values), the data is assumed to be:
- Population growth rate: 3.32%
- Fertility rate: 5.77
- Life expectancy: 63 years
### Step 3: Calculating Absolute Differences
We will calculate the absolute difference for each parameter and then sum these differences to find the total difference for each country.
#### Brazil:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - 0.83\right| = 0.85 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 1.81\right| = 0.20 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 73\right| = 3 \][/tex]
Total Difference for Brazil:
[tex]\[ 0.85 + 0.20 + 3 = 4.05 \][/tex]
#### Mexico:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - 1.24\right| = 1.26 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 2.20\right| = 0.59 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 76\right| = 6 \][/tex]
Total Difference for Mexico:
[tex]\[ 1.26 + 0.59 + 6 = 7.85 \][/tex]
#### Japan:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - (-0.14)\right| = 0.12 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 1.38\right| = 0.23 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 84\right| = 14 \][/tex]
Total Difference for Japan:
[tex]\[ 0.12 + 0.23 + 14 = 14.35 \][/tex]
#### Uganda:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - 3.32\right| = 3.34 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 5.77\right| = 4.16 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 63\right| = 7 \][/tex]
Total Difference for Uganda:
[tex]\[ 3.34 + 4.16 + 7 = 14.50 \][/tex]
### Step 4: Identifying the Closest Match
From the calculated total differences:
- Brazil: 4.05
- Mexico: 7.85
- Japan: 14.35
- Uganda: 14.50
The smallest difference is 4.05, corresponding to Brazil.
Thus, Russia compares most closely to Brazil based on the provided data.
### Step 1: Analyzing the Data

- Fertility rate: 2.20
- Life expectancy: 76 years
For Japan (hypothetical values), the data is assumed to be:
- Population growth rate: -0.14%
- Fertility rate: 1.38
- Life expectancy: 84 years
For Uganda (hypothetical values), the data is assumed to be:
- Population growth rate: 3.32%
- Fertility rate: 5.77

2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 1.81\right| = 0.20 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 73\right| = 3 \][/tex]
Total Difference for Brazil:
[tex]\[ 0.85 + 0.20 + 3 = 4.05 \][/tex]
#### Mexico:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - 1.24\right| = 1.26 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 2.20\right| = 0.59 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 76\right| = 6 \][/tex]
Total Difference for Mexico:
[tex]\[ 1.26 + 0.59 + 6 = 7.85 \][/tex]
#### Japan:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - (-0.14)\right| = 0.12 \][/tex]
2. Fertility Rate Difference:

3. Life Expectancy Difference:
[tex]\[ \left|70 - 84\right| = 14 \][/tex]
Total Difference for Japan:
[tex]\[ 0.12 + 0.23 + 14 = 14.35 \][/tex]
#### Uganda:
1. Population Growth Rate Difference:
[tex]\[ \left|-0.02 - 3.32\right| = 3.34 \][/tex]
2. Fertility Rate Difference:
[tex]\[ \left|1.61 - 5.77\right| = 4.16 \][/tex]
3. Life Expectancy Difference:
[tex]\[ \left|70 - 63\right| = 7 \][/tex]
Total Difference for Uganda:
[tex]\[ 3.34 + 4.16 + 7 = 14.50 \][/tex]
### Step 4: Identifying the Closest Match
From the calculated total differences:
- Brazil: 4.05
- Mexico: 7.85
- Japan: 14.35
- Uganda: 14.50
The smallest difference is 4.05, corresponding to Brazil.
Thus, Russia compares most closely to Brazil based on the provided data.
