Guild Abandonment
Server Sample: RP (High), PvE (Medium), PvE (High)
Sampling Period: Week 1: 6/10 - 6/17. Week 2: 07/05 - 07/12.
Sampling Resolution: ~14 minutes
Parsing Method: The sample unit is a guild. We tracked all guilds observed in the June week and counted the number of unique characters observed to belong to each guild. We then did the same for all guilds observed in the July week. We then tabulated whether a guild observed in June was observed again in July.
Data Filter: None
Sample Size: 2,744 guilds.
Of the 2,744 guilds observed in the one-week period in June, 21% were not observed again in the one-week period in July. However, many of these guilds (19%) were only observed with one character in June. If we only take into account guilds with more than one observed character in June, then 13% of those were not observed again in July. If we increase that criteria to guilds with at least 5 characters, then 7% of those were not observed again in July.
Of the guilds that were observed in both June and July (N = 2168), the average change in guild size was exactly 0. In other words, on average, guilds did not grow or shrink over the one month period. This was somewhat surprising given that we might have expected guilds to grow over time. In fact, if we exclude all "one-person guilds", the average change is mildly negative (-.13). On the other hand, the range of change in guild size was quite large even though the overall change was near 0. The largest loss was 103 and the largest gain was 87.
