Do dominant traits occur more often than recessive ?

Dominant traits are not always the most common. its common to think that a  dominant trait is the most likely to be found in the spot of  population, but the word "dominant" actually refers to the fact that the allele is expressed over another of a  allele. . . . . . . so not always i guess??

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
