A Query And Report That Shows The Total Number Of Pets
A Query And Report That Shows The Total Number Of Pets At The Animal S
A query and report that shows the total number of pets at the animal shelter and how many pets by type (e.g., cats, dogs). It should also display the youngest and oldest pet(s) along with their counts, and the total number of male and female pets.

Introduction
The management of animal shelters relies heavily on accurate data collection and reporting to ensure effective care and resource allocation. Key metrics such as the total number of pets, their distribution by type, age extremes, and gender composition are fundamental to understanding shelter demographics. This report demonstrates how to generate database queries to obtain these insights, culminating in comprehensive reports that support shelter operations and strategic planning.
Database Structure Assumption
The assumptions herein are that the shelter's database contains a table named `Pets` with the following essential columns:
- `PetID`: Unique identifier for each pet.
- `Name`: Name of the pet.
- `Type`: The species or type of pet (e.g., cat, dog, rabbit).
- `Age`: Age of the pet, stored as an integer representing years.
- `Gender`: Gender of the pet, stored as 'M' or 'F'.
This structure enables the construction of SQL queries to extract the required data.
Total Number of Pets and Pets by Type
To obtain the total number of pets and the count by each type, the following SQL queries are used:
```sql
-- Total number of pets
SELECT COUNT(*) AS TotalPets FROM Pets;
-- Number of pets by type
SELECT Type, COUNT(*) AS CountByType
FROM Pets
GROUP BY Type;
```
These queries provide a straightforward count of the entire shelter population and break it down into categories such as cats, dogs, etc.
Youngest and Oldest Pets
To identify the youngest and oldest pets, we leverage aggregate functions:
```sql
-- Find the youngest pet
SELECT COUNT(*) AS YoungestCount
FROM Pets
WHERE Age = (SELECT MIN(Age) FROM Pets);
-- Find the oldest pet
SELECT COUNT(*) AS OldestCount
FROM Pets
WHERE Age = (SELECT MAX(Age) FROM Pets);
```
These queries find the minimum and maximum ages in the database and count how many pets share these age extremes.
Gender Distribution
To analyze the gender distribution:
```sql
-- Count of male pets
SELECT COUNT(*) AS MaleCount
FROM Pets
WHERE Gender = 'M';
-- Count of female pets
SELECT COUNT(*) AS FemaleCount
FROM Pets
WHERE Gender = 'F';
```
This allows assessment of gender balance within the shelter.
Comprehensive Report
Combining all these queries into a comprehensive report can be achieved with view creation or combined SELECT statements in more advanced SQL implementations. For simplicity, separate queries can be executed to assemble the report.
A sample combined query for all metrics might look like:
```sql
SELECT
(SELECT COUNT(*) FROM Pets) AS TotalPets,
(SELECT COUNT(*) FROM Pets WHERE Age = (SELECT MIN(Age) FROM Pets)) AS YoungestCount,
(SELECT COUNT(*) FROM Pets WHERE Age = (SELECT MAX(Age) FROM Pets)) AS OldestCount,
(SELECT COUNT(*) FROM Pets WHERE Gender = 'M') AS MaleCount,
(SELECT COUNT(*) FROM Pets WHERE Gender = 'F') AS FemaleCount;
-- Counts by type
SELECT Type, COUNT(*) AS CountByType
FROM Pets
GROUP BY Type;
```
Data can be exported into reports via database management tools or integrated reporting software to generate formatted summaries.
Conclusion
Accurate and detailed pet data reporting is essential for effective shelter management. Using SQL queries to extract total counts, distribution by type, age extremes, and gender ratios provides vital insights. These reports support operational decision-making, resource planning, and improve overall shelter efficiency. Implementing such data analytics ensures the shelter maintains a healthy, well-managed environment for its animals.
