It was posted on Reddit that 226 of 876 (or 1/4) Kingdom Halls in Spain were sold during 2016. For many it sounds amazing and awesome. For me, this is implausible and needs fact-checking.
The above-mentioned figures come from bi-annual publications of The Observatory of Religious Pluralism in Spain (established by the Spanish Ministry of Justice, the Spanish Federation of Municipalities and Provinces, and the Pluralism and Coexistence Foundation). And yes, according to these publications, the number of KHs in Spain was 876 as of December 1, 2015, and 650 as of December 2016 - but also:
706 as of June 15, 2011,
703 as of June 20, 2012,
718 as of June 30, 2013, and
702 as of June 1, 2014,
701 as of June 1, 2015,
856 as of June 2016,
636 as of June 2018.
Does anybody believe JWs have build 175 Kingdom Halls (+25%) between June and December 2015 and have sold 206 (24%) ones a year later? I think not. I think the conclusion is obvious: the numbers of KHs for Dec 2015 and June 2016 are anomalous, the result of an error or a different methodology. The number of Kingdom Halls declined, but not so drastically - by 51 (7%) between June 2015 and December 2016.
