Methodology

As mentioned in the related article 2019 Most Common LEGO Parts, my original goal in preparing this list was to determine which parts are actually most common for an upcoming 2019 refresh to the popular 2018 article Hard-to-Find LEGO Colors (and what to do about it).

Data Analysis Methodology:

  1. I downloaded the latest database files from rebrickable, and re-created the same relationships in Microsoft Access.
  2. I created supplementary tables containing preferred part names, current part colors, parts or part categories to remove from the analysis, and corrected part ID’s. (Identical parts with different Part ID’s, and nearly identical parts were merged as one part for the purposes of this analysis.)
  3. I created queries which simplify the dataset for the purposes of this analysis. This includes a table listing the number of pieces of each element you would get if you bought every set in a given year. The resulting table has 1/6 fewer rows than the rebrickable_Inventory_parts table it is derived from (which has 3/4 million rows.)
  4. This data is imported into Excel, where I have tables containing element quantities for each 5-year span starting from 2010.
  5. Lastly, I created a table where I can compare quantity of each part across different 5-year spans, and output the results in HTML.

There are several possible errors in the methodology used for this analysis:

  • Errors in Rebrickable dataset – Any errors in the Rebricable database will be reflected in this analysis. The biggest source of errors I’ve detected so far is that many printed parts are not in one of the printed categories (Printed Bricks, Printed Tiles) for easy removal from the analysis. (Groups are specified in the rebrickable_part_categories table.)
  • Errors in my queries – I had not written SQL queries in 15+ years, so I might have made a mistake!
  • Errors in my analysis – The analysis included many manual steps, where I might have made mistakes.

The part images used in this article were created using scripts similar to those used to create my LEGO Brick Labels collection. (These images are smaller, and have lower contrast optimized for screen.)

Please let me know if you see any errors in the data or my methodology. Thanks!
