sscanf can extract formatted text well. e.g.:

sscanf("WA 053 011 Clark County             45","%*2c %*3d %3d %*25c %d")
sscanf("WA 053 027 Grays Harbor County      100,"%*2c %*3d %3d %*25c %d")

You can use fscanf to read the whole file:

fid = fopen("data.txt") ;
data = fscanf(fid,"%*2c %*3d %3d %*25c %d\n",[2,inf]) ;
fclose(fid) ;
cntys = data(1,:).' ;
data = data(2,:).' ;
