How accurate is the WMIL information?
We strive to be as accurate as we can with each data category. Where possible, we go to primary sources such as the US Census Bureau. However, in some cases, we have to assemble data from multiple locations where the sources are not well documented and may not be up-to-date. Therefore, if a specific criterion is essential to you (e.g., snowfall in a particular city), you may want to secure data independently from trusted authorities.
In other cases, such as the data surrounding nuclear attacks, the data is purely speculative. Should there ever be a nuclear attack on the United States (heaven forbid!), the attackers have not exactly provided their military strategy. In this case, speculations appear to be based on military targets (e.g., bases, missile silos, etc.) and large population centers.
