I've known about Radix for several years, and it is an increasingly valuable site for those who want to trace their roots to Hungary. RADIX has over 900 links... You can find some interesting statistical information here for starters such as
Emigration from Hungary to the USA 1899-1913. Data of Hungarian counties.
Emigration from Hungary / the figures of European ports between 1871-1913
The ethnic division of immigrants from Hungary to the USA between 1900-1912
Immigrants from Hungary to the USA 1898-1913 : Break-down by states
