I found two related articles with surveys on dating preferences based on the racial background. The data is from OkCupid (online dating website). Answers from over 1 million people were taken into account, so it is a big survey (hence also fairly reliable).
Birds of a feather flocking together
Here we see that a much higher percentage of White people prefer to stick to their own racial* group. The gap with other races is huge. 54% of White females and 40% of White males strongly prefer to date someone who is also White. The average for non-Whites is only 20%. At the bottom, only 11% of Black males say that they only want to date Black women.
The second article gives more precision about the perceived attractiveness from one specific racial group to another, both from the males and females' point of view.
Patterns of response rates on OkCupid by sex & race
Here we see that Black women are the least popular, with 31 to 41% of males replying to them. Middle-Eastern females are the most popular, with 47 to 63% of men responding to their inquiries, followed by White and Asian females. What is surprising is that men almost always prefer Middle-Eastern women to women from their own racial background, except ironically for Middle-Eastern men who prefer Pacific Islander females.
When receiving a inquiry from a man, Black and Native American women were the most likely to reply, while Asian, Hispanic and White women were the least disposed to.
*the definition I use for "racial group" is based on continental and subcontinental divisions, which is different from the "ethnic groups" that subdivide a race. For instance, White/European is a racial group, while Basque or Finn would be an ethnic group.
