Group Statistics

The top 9 groups with the highest average membership from 2005 to 2022.

About this data

The information on this page was manually gathered from the official statistics page which was archived by the Wayback Machine. The WBM archived the page over 300 times between 2005 and 2022. Group and population data for the game is not backed up by the game server and is lost every time it is updated, so a great amount of population and group data has been lost.

The official statistics page only lists groups with 10 or more active members, i.e players who performed an action in the last 5 days. According to this data there have been exactly 1,100 groups that have had at least 10 members at one point in time. Many of these were short lived groups but there are several groups which have continued to play since the game began in 2005. This figure must be close to the true number of total groups because this wiki has 1,542 group related pages.

The Ridleybank Resistance Front (RRF) is the only group which has never fallen below 10 active members, making it the oldest group in the game.

The Dead hold the record for largest amount of members on a single date, 1,751 members on 1/5/2011. According to the server manager The Dead have a total group size of 7,266 if you take into account inactive players, a statistic that cannot be seen by regular players.

Yearly group Records

The top 10 groups with the highest average membership from 2005 to 2022. Unlike the graph at the top of this page, this graph also includes The Dead.

This table shows the records for the highest group size of each year based on the available data. Despite the lack of data, the effect of protest groups on the game is obvious. Zerging became a major problem in the last few years so the results are certainly effected by this. The amount of Wayback Machine Captures has been included to indicate the sample size.
