Introduction

This project focuses on analyzing job posting data related to Data Analyst roles.
By using SQL (PostgreSQL) as the primary tool for querying and data exploration, the project aims to uncover trends in salaries, hiring companies, job locations, and the skills most in demand.
The purpose of this analysis is to translate raw job data into valuable insights that reflect the current state of the Data Analytics job market.
It serves as both a learning exercise in SQL and a practical exploration of how structured query language can reveal patterns in real-world employment data.

Background

The dataset used in this project comes from the SQL Course

It includes multiple dimensions such as:

  • Company details – information about the employer and hiring organization
  • Job titles and roles – description and categorization of each position
  • Location types – remote, hybrid, and on-site job opportunities
  • Salary information – annual average salary data where available
  • Posting details – job posting date, schedule type, and other attributes

The goal of analyzing this dataset is to understand the factors that influence salaries, hiring patterns, and demand for analytical skills.
This project reflects how data-driven insights can help professionals and students identify valuable trends in the growing Data Analytics job market.

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

  • PostgreSQL – used for executing SQL queries, data exploration, and analysis
  • Visual Studio Code – the main editor for writing and managing SQL scripts
  • Git & GitHub – for version control, tracking changes, and sharing the project
  • Excel / CSV Files – used as data sources imported into PostgreSQL for analysis

These tools together provided a complete workflow for performing data analysis — from raw data extraction to structured insights and documentation.

Analysis

1. Top Paying Jobs

To identify top paying job roles, I filtered Data Analyst positions by yearly average salary and job location, focusing on remote jobs, this query highlights top paying jobs in the field.

Key Insights

  • Wide Salary Range : Top 10 Data Analyst job roles have salaries ranging all the way from $184K to $650K, indicating significant salary potential in the field.
  • Diverse Employers : Companies like Mantys, Meta, AT&T, etc. are those offering high salaries, showing a broad interest in this field.
  • Job Title Variety : There is a variety of job titles in this field, ranging from Data Analyst to Associate Director - Data Insights, indicating various specializations within the role.

The chart below visualizes the Top 10 Highest Paying Data Analyst Jobs.
It provides a quick comparison of salary ranges across companies for remote roles.

2. Skills required for Top Paying Jobs

After identifying the highest-paying Data Analyst jobs, I focused on understanding which skills were most commonly associated with those roles.
The goal was to discover what technical expertise employers value most when offering higher compensation.

Key Insights

  • SQL and Python consistently appear among the highest-paying roles, confirming their dominance in the analytics space.
  • Advanced tools like Snowflake, Azure, and Tableau are highly valued by companies offering six-figure salaries.
  • Employers paying top salaries tend to prefer candidates with data engineering and cloud-related skills, not just data analysis expertise.
  • Skills associated with data visualization and database management also correlate strongly with higher pay.

The chart below visualizes the Top Skills Associated with the Highest Paying Jobs in Data Analytics.

3. High Demand Skills

In this section, I analyzed which skills are most frequently required in Data Analyst job postings, regardless of salary.
The purpose was to identify the technical competencies that are currently in highest demand across the industry.

Key Insights

  • SQL is the most universally required skill, appearing in the majority of Data Analyst job postings.
  • Excel remains highly relevant, reflecting its continuing importance for quick data manipulation and reporting.
  • Python and Tableau are increasingly dominant, signaling the shift toward programmatic analysis and data visualization.
  • Power BI, R, and SAS appear in more specialized analytics roles, showing a trend toward data integration and advanced statistical modeling.
  • Employers prioritize core analytical and visualization skills over niche or emerging tools.

The chart below visualizes the Top 5 Most In-Demand Skills for Data Analysts, providing a clear picture of where aspiring analysts should focus their learning efforts.

High Demand Skills

These findings highlight that while advanced tools offer an edge, mastering the foundational trio — SQL, Excel, and Python — is essential for success in the analytics job market.

4. Top Paying Skills

This section explores which skills lead to higher salaries for Data Analysts.
Rather than just looking at demand, the focus here is on identifying which specific technical competencies are associated with above-average compensation.

Key Insights

  • Big Data and Cloud Tools such as Snowflake, Azure, and AWS rank among the top-paying skills.
  • Programming Languages like Python and R remain valuable for both analytics and advanced modeling tasks.
  • Database and Query Tools like SQL continue to serve as a baseline skill — essential for any analyst role.
  • Companies rewarding higher pay often seek professionals comfortable with data warehousing, pipeline management, and automation.

The chart below shows the Top 10 Highest Paying Skills for Data Analysts, providing a visual representation of how technical expertise influences earning potential.

Top Paying Skills

In conclusion, while foundational skills such as SQL and Python are mandatory, developing proficiency in cloud technologies and advanced analytics tools significantly boosts salary prospects in the field of Data Analytics.

5. Most Optimal Skills

After analyzing both high-demand and high-paying skills, this section focuses on identifying which skills strike the best balance between demand and salary.
These are the “sweet spot” skills that maximize employability while also providing strong compensation opportunities.

Key Insights

  • SQL, Python, and Tableau appear in the overlap between high-demand and high-paying skills, confirming their importance as foundational tools.
  • R and Power BI provide strong salary potential for analysts looking to specialize in statistics and visualization.
  • Skills related to cloud platforms (such as Snowflake and Azure) add a significant competitive advantage in the job market.
  • The most optimal strategy for aspiring Data Analysts is to master core analytics tools first, then branch into cloud and visualization technologies.

The chart below displays the Most Optimal Skills for Data Analysts, combining demand and salary insights into one visual reference.

Most Optimal Skills

In summary, the analysis reveals that focusing on a blend of core analytical, visualization, and cloud-based skills creates the strongest career advantage in the modern data landscape.
