What does pop report mean?
A population report is a census provided by grading companies that lists the total number of a specific card ever graded and provides a breakdown of how many copies exist at every grade level.
A Population Report, or "pop report," is a publicly accessible database maintained by third-party grading companies—primarily Professional Sports Authenticator (PSA), Beckett Grading Services (BGS), and Certified Sports Guaranty (CSG)—that catalogs every card ever certified by that firm. Collectors use these reports to determine the scarcity of a card in a specific condition, which directly correlates to its market value.
The report breaks down data by the card’s year, set name, player name, and variation. It then lists the total number of copies graded at every numerical level (1 through 10). For example, a 1986 Fleer Michael Jordan #57 might have over 25,000 total copies graded by PSA, but only 322 of those are designated as PSA 10 (Gem Mint) as of late 2023. These 322 copies are referred to as the Pop 1, meaning they represent the highest tier of available quality.
To analyze a pop report effectively, collectors look for two key metrics:
- Total Population: The total number of all graded examples of a specific card.
- Pop Higher: The number of copies that exist in a grade better than the one currently being viewed. If a card is a Pop Higher 0, it is a "none top" or the best condition known to exist.
High population numbers often lead to price stagnation because the supply meets or exceeds demand. Conversely, "Low Pop" cards (often seen in vintage sets or high-end modern parallels like Panini Prizm Gold) command significant premiums because they are objectively rarer than their lower-graded counterparts. Investors use these reports to spot "condition rarities," where a common card is worth thousands simply because the pop report shows it is nearly impossible to find in a perfect grade.
Pop reports are updated in real-time as cards are processed. However, they can be slightly inflated by "crack and resubmits," where a collector breaks a card out of its plastic holder (slab) and sends it back in hopes of a higher grade without returning the original label to the grading company to be deleted from the database.

What is a Pop 1 card? Great for scarcity.
A 'Pop 1' card is a 'Population 1' item, meaning it is the only specimen in the world to have received that specific grade from that grading company.
How do I know if my card is a 'Top Pop'?
Check the 'Pop Higher' column on a PSA or BGS report; if it is zero, your card is a 'Top Pop' and holds the highest grade currently assigned to that issue.
Are population reports 100% accurate?
Pop reports can be slightly inaccurate due to 'resubmissions,' where collectors crack open slabs to regrade cards without the old certification numbers being removed from the database.
Why does a low pop report increase card value?
A low pop indicates high scarcity in a specific grade, often allowing a common card to sell for thousands of dollars due to the difficulty of achieving a high condition mark.
