In​ 2015, there were approximately 3,763,000 births in the country. Find the birth rate in births per minute. Assuming a population of 324 ​million, what was the annual birth rate in units of births per 1000​ people?

To solve the problem, we need to find two things:

### 1. **Birth rate in births per minute**:
   - There are 3,763,000 births in a year.
   - There are 365 days in a year, 24 hours in a day, 60 minutes in an hour.

First, we find the total number of minutes in a year:
\[
\text{Minutes per year} = 365 \times 24 \times 60 = 525,600 \, \text{minutes}
\]

Now, we can calculate the birth rate per minute:
\[
\text{Births per minute} = \frac{3,763,000 \, \text{births}}{525,600 \, \text{minutes}} \approx 7.16 \, \text{births per minute}
\]

### 2. **Annual birth rate in units of births per 1000 people**:
   - Total population = 324 million = 324,000,000 people.
   - The birth rate per 1000 people can be found by dividing the total number of births by the population and then multiplying by 1000.

\[
\text{Annual birth rate per 1000 people} = \frac{3,763,000}{324,000,000} \times 1000 \approx 11.61 \, \text{births per 1000 people}
\]

### Final answers:
1. The birth rate is approximately **7.16 births per minute**.
2. The annual birth rate is approximately **11.61 births per 1000 people**.

Would you like more details or have any questions? Here are some related questions to expand on:

1. How would the birth rate change if the population increased?
2. How do countries with higher birth rates compare in terms of population growth?
3. What is the difference between the crude birth rate and fertility rate?
4. How can changes in birth rates affect a country's economy?
5. How are birth rates related to a country’s healthcare system?

**Tip**: When calculating per-minute rates, always check the number of days in the year (consider leap years too!).
