How to read the data

The figures on this site come from public-source pop-up records and Seoul public data. Each source counts something different and has its own limits. Please read the notes below alongside the figures.

Pop-up records

What it counts
Pop-ups held in Seongsu, gathered from public sources with the same pop-up merged into one record. Counted by start date.
Source and unit
We combined pop-up information platforms (Popply, Popga, HeyPop), the official social accounts and websites of brands and venues, press releases and news articles, and magazines, and merged the same pop-up into one record (2021-10-15 to 2026-10-17, collected 2026-10-17). Pop-ups with no official source found are marked "Original source unverified". New pop-ups are added once a week.
Watch for
  • Only pop-ups known through public sources are included. Pop-ups that were never announced are missing.
  • Before May 2023 there were no weekly lists or platform data, so records rely mostly on articles and are undercounted.
  • For pop-ups after October 16, 2026, pop-up information platforms are not read and only those known through articles and official social accounts are added, so they are counted less than before.
  • More records do not mean better results. When comparing periods with different collection coverage, keep this difference in mind.

Estimated sales

What it counts
Quarterly sales of permanent stores, estimated by the Seoul Commercial District Analysis Service from card payment data.
Source and unit
Seoul Commercial District Analysis Service (Seoul Open Data Plaza), quarterly, KRW.
Watch for
  • These are estimates, not actual sales.
  • They are sales of permanent stores and do not indicate pop-up results.
  • When you choose a category, only the Seoul business types that match that category are added. Categories with no matching Seoul business type (Exhibitions & entertainment, Other) do not show sales.

Store count

What it counts
Store counts from the Seoul Commercial District Analysis Service: all stores, independent and franchise combined.
Source and unit
Seoul Commercial District Analysis Service (Seoul Open Data Plaza), quarterly, stores.
Watch for
  • Only stores classified under Seoul service business types are counted.

Street foot traffic

What it counts
The number of people passing along streets in the district, as estimated by the Seoul Commercial District Analysis Service.
Source and unit
Seoul Commercial District Analysis Service street-level population, quarterly, people.
Watch for
  • It is an estimate and the same regardless of category.
  • It is not the number of people who entered a store.

Seoul living population (Korean residents, short-term foreign visitors)

What it counts
The number of people inside each 250 m grid cell at a given hour, added up by district share. “Avg. people at an hour” on screen is the hourly average of this value.
Source and unit
Seoul living population (Korean residents, short-term foreign visitors), by date and hour, people.
Watch for
  • It is not a daily visitor count. People who live, work or stopped by are all included.
  • Seoul masks cells with 3 people or fewer, and these are counted as 0, so values may be lower than reality (a lower bound).
  • Gender, age and nationality breakdowns are shares within unmasked cells, so the known share is shown alongside.

District boundaries and split values

What it counts
Seongsu is viewed as 10 local districts. Boundaries follow roads and administrative lines.
Source and unit
Public figures add each Seoul trade area's value multiplied by the share of its stores inside this district (taken whole at 95% or more). Road and administrative boundaries © OpenStreetMap contributors.
Watch for
  • Districts that span several Seoul trade areas are split estimates and are marked “est.” on screen.
  • Pop-up records outside the boundaries are not included in district figures.

No data versus 0

What it counts
“No data” means no data has come in for that quarter and district. 0 means there is data and the value is 0.
Source and unit
If there is no data for the same quarter a year earlier, the change is also “No data”.
Watch for
  • Values with too few records to calculate reliably (such as typical run) show the record count and a note instead of a value.

When it changes

What it counts
Pop-up records are collected and added once a week. Seoul public data is checked and added by a person when a new quarter is released. Living population shows the period that has been loaded.
Source and unit
The period and update date of each dataset are in “Data status” below.
Watch for
  • This is not real-time data.
