Answer:
From what Ive seen here in Texas, The avg. Male height seems to vary between 5'10" and 6'3". Females on the other hand seem to be between 5'3" and 5'8" on average. Ive also noticed that race seems to factor in a bit. For example Most Hispanic males here tend to be between 5'5" & 5'9", shorter than many whites & Africans. I myself are a male Hispanic, At a height of 5'10".
