Almost every fiftyfive boy's first name in the USA begins with the letter O…
This means that the initial O 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. The distribution of initial letters is undoubtedly uneven – after all, some letters occur much more frequently, while others are much less frequent. In the US, the most common initials among boys' first names are J and A, while the letters U and X, on the other hand, are initials for very few names.
