The percentage of the sample population with brown eyes and black hair is 21.122112211221122%.

The percentage of the sample population with blue eyes and black hair is 2.9702970297029703%.

The difference between these percentages is 18.151815181518153%.

When rounded to the nearest whole number, the answer is 18%.

Therefore, the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18 percentage points.
