Background

Driven by a quest to navigate the data analyst job market more effectively, this project was born from a desire to pinpoint top-paid and in-demand skills, streamlining others work to find optimal jobs.

Data hails from SQL Course. It's packed with insights on job titles, salaries, locations, and essential skills.

The questions I wanted to answer through mySQL queries were:

1. What are the top-paying data analyst jobs?
2. What skills are required for these top-paying jobs?
3. What skills are most in demand for data analysts?
4. Which skills are associated with higher salaries?
5. What are the most optimal skills to learn?

Tools I Used

For my deep dive into the data analyst job market, I harnessed the power of several key tools:

• SQL: The backbone of my analysis, allowing me to query the database and unearth critical insights.
• PostgreSQL: The chosen database management system, ideal for handling the job posting data.
• Visual Studio Code: My go-tog for database management and executing SQL queries.
• Git & GitHub: Essential for version control and sharing my SQL scripts and analysis, ensuring collaboration and project tracking.

The Analysis

Each query for this project aimed at investigating specific aspects of the data analyst job market. Here's how I approached each question:

1. Top Paying Data Analyst Jobs

To identify the highest-paying roles I filtered data analyst positions by average yearly salary and location, focusing on remote jobs. This query highlights the high paying opportunities in the field.

SELECT
    job_id,
    job_title,
    job_location,
    job_schedule_type,
    salary_year_avg,
    job_posted_date,
    name AS company_name
FROM
    job_postings_fact
LEFT JOIN company_dim ON job_postings_fact.company_id = company_dim.company_id
WHERE 
    job_title_short = 'Data Analyst' AND
    job_location = 'Anywhere' AND
    salary_year_avg IS NOT NULL
ORDER BY 
    salary_year_avg DESC
LIMIT 10;

Here's the breakdown of the top data analyst jobs in 2023:

• Wide Salary Range: Top 10 paying data analyst roles span from $184,000 to $650,000, indicating significant salary potential in the field.

• Diverse Employers: Companies like SmartAsset, Meta, and AT&T are among those ottering high salaries, showing a broad interest across different industries.

• Job Title Variety: There's a high diversity in job titles, from Data Analyst to Director of Analytics, reflecting varied roles and specializations within data analytics.

2. Top Paying Data Analyst Skill

To identify the highest-paying skills I filtered data analyst positions by average yearly salary and job title, focusing on remote jobs. This query highlights the skills with the high paying opportunities.

WITH top_paying_jobs AS (
    SELECT
        job_id,
        job_title,
        salary_year_avg,
        job_posted_date,
        name AS company_name
    FROM
        job_postings_fact
    LEFT JOIN company_dim ON job_postings_fact.company_id = company_dim.company_id
    WHERE 
        job_title_short = 'Data Analyst' AND
        job_location = 'Anywhere' AND
        salary_year_avg IS NOT NULL
    ORDER BY 
        salary_year_avg DESC
    LIMIT 10
)
SELECT
    top_paying_jobs.*,
    skills
