The question asks for calculating the average monthly and yearly population growth of city A, based on the given chart showing the number of births and deaths for the first four months.

To solve this, we need to:

1. Extract the monthly birth and death counts from the chart.
2. Calculate the net population growth for each month by subtracting deaths from births.
3. Find the average monthly growth by adding the net growths and dividing by 4.
4. Multiply the average monthly growth by 12 to estimate the annual growth.

I'll analyze the chart and continue from there.After reviewing the chart details:

### Step 1: Monthly Birth and Death Counts
From the chart, we observe the following birth (blue bars) and death (orange bars) counts for each month:

- **January**: Births = 1355, Deaths = 1507
- **February**: Births = 1098, Deaths = 1289
- **March**: Births = 1156, Deaths = 1578
- **April**: Births = 1255, Deaths = 1335

### Step 2: Monthly Net Growth Calculation
For each month, net growth is calculated as:
\[
\text{Net Growth} = \text{Births} - \text{Deaths}
\]
- **January**: \(1355 - 1507 = -152\)
- **February**: \(1098 - 1289 = -191\)
- **March**: \(1156 - 1578 = -422\)
- **April**: \(1255 - 1335 = -80\)

### Step 3: Average Monthly Growth
\[
\text{Average Monthly Growth} = \frac{-152 + (-191) + (-422) + (-80)}{4} = \frac{-845}{4} = -211.25
\]

### Step 4: Estimated Annual Growth
\[
\text{Estimated Annual Growth} = -211.25 \times 12 = -2535
\]

### Conclusion
The average monthly population change is approximately \(-211\) people, and the estimated annual population decrease is around \(-2535\) people.
