Reduce skew on a table with Shapefile data?

I downloaded this Geospatial Shapefile:

https://www2.census.gov/geo/tiger/TIGER2015/UAC/

The table that was created by loading the shapefile looks like this:

CREATE SET TABLE myDatabaseHere.tl_2015_us_uac10,NO FALLBACK ,

     NO BEFORE JOURNAL,

     NO AFTER JOURNAL,

     CHECKSUM = DEFAULT,

     DEFAULT MERGEBLOCKRATIO

     (

      UACE10 VARCHAR(5) CHARACTER SET LATIN NOT CASESPECIFIC,

      GEOID10 VARCHAR(5) CHARACTER SET LATIN NOT CASESPECIFIC,

      NAME10 VARCHAR(100) CHARACTER SET LATIN NOT CASESPECIFIC,

      NAMELSAD10 VARCHAR(100) CHARACTER SET LATIN NOT CASESPECIFIC,

      LSAD10 VARCHAR(2) CHARACTER SET LATIN NOT CASESPECIFIC,

      MTFCC10 VARCHAR(5) CHARACTER SET LATIN NOT CASESPECIFIC,

      UATYP10 VARCHAR(1) CHARACTER SET LATIN NOT CASESPECIFIC,

      FUNCSTAT10 VARCHAR(1) CHARACTER SET LATIN NOT CASESPECIFIC,

      ALAND10 FLOAT,

      AWATER10 FLOAT,

      INTPTLAT10 VARCHAR(11) CHARACTER SET LATIN NOT CASESPECIFIC,

      INTPTLON10 VARCHAR(12) CHARACTER SET LATIN NOT CASESPECIFIC,

      GEOM SYSUDTLIB.ST_Geometry)

PRIMARY INDEX ( UACE10 );

The skew is 91.53%, what can be done to reduce the skew?
