Calculate: 1. Infant mortality rate 2. Stillbirth rate 3. Perinatal mortality rate 4. Under-five mortality rate

$$\text{Infant Mortality Rate} = \frac{\text{Deaths of children < 1 year}}{\text{Total live births}} \times 1,000$$ $$\text{Infant Mortality Rate} = \frac{145}{2,380} \times 1,000$$ $$\text{Infant Mortality Rate} \approx 60.924$$

1. Infant mortality rate: $\boxed{\text{60.92 per 1,000 live births}}$

$$\text{Stillbirth Rate} = \frac{\text{Number of stillbirths}}{\text{Total live births} + \text{Total stillbirths}} \times 1,000$$ $$\text{Stillbirth Rate} = \frac{85}{2,380 + 85} \times 1,000$$ $$\text{Stillbirth Rate} = \frac{85}{2,465} \times 1,000 \approx 34.483$$

2. Stillbirth rate: $\boxed{\text{34.48 per 1,000 total births}}$

$$\text{Perinatal Mortality Rate} = \frac{\text{Stillbirths} + \text{Early Neonatal Deaths}}{\text{Total live births} + \text{Total stillbirths}} \times 1,000$$

The problem states that "deaths occurring 28 weeks gestation to 7 completed days of life in 2017 is 258", which represents the sum of stillbirths and early neonatal deaths.

$$\text{Perinatal Mortality Rate} = \frac{258}{2,380 + 85} \times 1,000$$ $$\text{Perinatal Mortality Rate} = \frac{258}{2,465} \times 1,000 \approx 104.665$$

3. Perinatal mortality rate: $\boxed{\text{104.67 per 1,000 total births}}$

$$\text{Under-five Mortality Rate} = \frac{\text{Deaths of children < 5 years}}{\text{Total live births}} \times 1,000$$ $$\text{Under-five Mortality Rate} = \frac{328}{2,380} \times 1,000$$ $$\text{Under-five Mortality Rate} \approx 137.815$$

4. Under-five mortality rate: $\boxed{\text{137.82 per 1,000 live births}}$
