Of all boys' first names in the United States, only about 1.5 % begin with the letter P…
This means that the initial P 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, 3.8 % is just the average. Of course, the initials of boys' first names aren’t that evenly distributed, with some letters being rarer than others. In the US, the initials J and A are particularly frequent for boys' first names, while very few names begin with the letters U and X.
