If you have 150 accounts in the club system, and the average household is, say 2,5, then the number of individuals (including children) rises to 375. This number starts to rise up to the Clan size.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Tribal group, interestingly, corresponds to voting districts of the smallest size ( elating to walking distance to a polling station). <a href=\"https:\/\/146help.avbp.net\/index.php\/2021\/11\/03\/voting-districts-post-codes-and-146\/\" data-type=\"post\" data-id=\"247\">Read more here.<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, the club&#8217;s aim might be to exert influence on people around them. Some research suggests that at 25% of any group, a tipping point is reached where, given the right circumstances, the whole group can suddenly change. <a href=\"https:\/\/146help.avbp.net\/index.php\/2021\/11\/14\/aim-for-25-heres-why\/\" data-type=\"post\" data-id=\"266\">Read more here.<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>References:<\/strong><br><a href=\"http:\/\/www.theagileelephant.com\/dunbars-numbers-and-organising-for-social-business\/\">Agile Elephant<\/a><br>Dunbar, R.
