No. There are equal quantities, north and south. One must
consider land mass and population density when dealing with
meteorites. Most meteorites end up in the ocean. However,
there is more land in the north for meteorites to be found on.
All of North America, Central America and part of South
America plus all of Eurasia and half of Africa in the north.
Australia, half of Africa and most of South America in the
south.
The island chains in the south pacific are evenly split while
Greenland and Antarctica are shielded from dense falls/finds
by their respective latitudes.
Regardless, neither hemisphere gets a higher quantity of
meteorites.
