1. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of identifying one or more high-ranking sectors that require additional communications resources in a wireless network that includes a plurality sectors serving multiple wireless-service subscribers, the method comprising: identifying a set of churners that are wireless-service subscribers that have churned during a given period of time; for each of the plurality of sectors, capturing by the computing device customer profile data, usage data, and terrain data related to the set of churners for a pre-churn time period that is a first period that precedes said given time period; ranking by the computing device the plurality of sectors based on a probability of each sector to produce churners, wherein the probability of each sector to produce churners is based on the customer profile data, the usage data, and the terrain data for that sector, wherein ranking the plurality of sectors includes ranking the plurality of sectors based on the probability that each of the plurality of sectors is one of the top five percentile churning sectors; determining one or more reasons for each of the plurality of sectors being ranked and including the one or more reasons with each ranking, wherein the one or more reasons include high ratio of blocked calls and a high ratio of failed connection attempts; and identifying by the computing device one or more high-ranking sectors that require additional communications resources based on the ranking.
