LinkedIn Industries List & Rankings (2021)

Updated: Oct 12, 2022

2020 was about as kind to LinkedIn as it was to the rest of us. Over the course of 2020, LinkedIn's total network size actually decreased from 448M members in 2020 to 428M in 2021. On a more positive note, there were some changes to the top 10 industries, as well as 1 new industry added to the list!

But before we get to that, a bit of history for those of you that may be new to the rankings. LinkedIn requires all of its members to declare which of their 148 industry codes best categorizes their professional activity. You are required to do this first as a new member to the platform, and then you can subsequently change your industry code as you like. The codes have evolved over the years and different industries have risen and fallen in popularity, but the fact that LinkedIn allows us to search for profiles by industry makes it an the world's most powerful tool for selling and job hunting, and allows us to understand a bit more about the evolutions of the world's professions.

In this post, we'll once again perform our annual duty of zooming into the market share of the top 10 industries on LinkedIn and then we'll share the full list of LinkedIn's 148 industries (sorted from largest to smallest). All of this data was extracted from LinkedIn in January 2021.

The Top 10 Industries on LinkedIn

As of January 2021, LinkedIn has slightly over 428 million individual accounts (down from 448 million in 2020) with the top 10 industries comprising 27% of all profiles on the network (the top 25 industries comprise over 52% of all profiles).

The top 10 industries are:

  1. Information Technology & Services

  3. Construction

  4. Retail

  5. Education Management

  6. Financial Services
