Introduction

📊 Focusing on data analyst roles, this project explores 💰 top-paying jobs, 🔥 in-demand skills, and 📈 where high demand meets high salary in data analytics.

🔍 Check out SQL Queries here: project_sql folder

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.

The Dataset used was obtained from the youtuber and content creator Luke's Barousse on his SQL Course. It's packed with insights on job titles, salaries, locations, and essential skills.

The questions I wanted to answer through my SQL 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 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-to 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.

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 jp.job_id, 
       jp.job_title,
       jp.job_location,
       jp.job_schedule_type,
	   jp.salary_year_avg,
	   jp.job_posted_date,
       cp.name as company

from job_postings_fact jp
join company_dim cp on jp.company_id = cp.company_id

where jp.salary_year_avg is not null 
and jp.job_title_short = 'Data Analyst'
and jp.job_location = 'Anywhere'

order by jp.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 offering 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.

from job_postings_fact jp
join company_dim cp on jp.company_id = cp.company_id

where jp.salary_year_avg is not null 
and jp.job_title_short = 'Data Analyst'
and jp.job_location = 'Anywhere'

order by jp.salary_year_avg desc
limit 10

)

select tpj.*, sd.skills
from top_paying_jobs tpj
join skills_job_dim sjd on sjd.job_id = tpj.job_id
join skills_dim sd on sd.skill_id = sjd.skill_id
order by tpj.salary_year_avg desc
