Only about one in 60 boys' first names in the US begins with the letter Y…
This means that the initial Y is found much less frequently than average. On average, each letter appears as an initial in about 3.8 % of all boys' names, considering the 26-letter English alphabet. However, the average is only a median, as initials aren't completely evenly distributed, of course. Some letters are more commonly found as initials than others. Most boys' first names in the US start with the letters J and A, while the initials U and X are the least common.
