Mini SQL Project Kit: Opioid ED Visit Analysis

💊 SQL Project: Analyze Opioid Overdose Data

Turn messy public health data into meaningful insights — with SQL.

Whether you’re just starting out or brushing up your skills, this beginner-friendly SQL project is the perfect way to build confidence and practice real-world health data analysis.

Inside, you’ll get a step-by-step guide and dataset structure to explore opioid-related emergency visits, calculate rates, and uncover demographic and geographic trends — just like analysts do at health departments, research centers, and public health organizations.

🔍 What You’ll Learn

This project gives you hands-on practice with SQL skills that matter in healthcare analytics:

• Data Cleaning with WHERE and IS NULL → flag missing visit data and ICD-10 codes
• Date Functions (YEAR, EXTRACT) → analyze overdoses by year and month
• Aggregations + Grouping → summarize visits by sex, age group, and county
• Joins for Context → combine ED data with population tables to calculate per-capita rates
• Identifying Repeat Patients → use GROUP BY + HAVING to detect high-risk individuals with multiple overdose visits

You won’t just write queries — you’ll learn how to think like a public health analyst, using SQL to uncover insights that inform policy and interventions.

🧠 Why This Project Matters

"I never realized how powerful SQL could be until I used it to analyze opioid overdose data. Seeing how queries could highlight hotspots and high-risk groups showed me what real impact data can have."

That’s the kind of experience this project gives you.

You’ll move beyond memorizing syntax — and start practicing the kind of analysis public health teams depend on to guide decisions.

📦 What’s Included

• A clean, beginner-friendly schema to mimic ED visit data
• A step-by-step SQL guide (perfect for solo practice or study groups)
• Pre-written SQL queries + explanations to reinforce learning
• Example visuals + portfolio prompts so you can turn this into a case study

✅ Perfect For:

• Students in public health, epidemiology, or data analysis
• Career switchers moving into health analytics
• SQL beginners who want something more applied than toy datasets
• Anyone curious how data can be used to address the opioid crisis

🚀 Real Skills. Real Data. Real Practice.

Forget endless tutorials with no real-world connection. This project mimics what health analysts actually do — explore ED visits, measure trends, and make sense of messy healthcare data.
