As of August 27, 2018, how many people in the United Kingdom were reported to be over the age of 110?

The answer is based on demographic statistics that report on the population of supercentenarians, individuals aged 110 and over. As of the specified date, August 27, 2018, the figure that is widely acknowledged and verified indicates that there were indeed 6 people in the United Kingdom who reached or surpassed the age of 110. This number reflects the reality of life expectancy and the occurrence of very elderly individuals in the population, which is a relatively rare phenomenon.

Given that the other figures don't align with the recorded data—there were not as many as 4, 8, or 10 known individuals over that age in the UK at that time—the correct choice emphasizes the verified demographic data for supercentenarians, supporting the answer of 6 as the accurate count. These statistics can fluctuate, but on the date given, the number stood firmly at 6, solidifying the choice.
