{
     jurisdiction: name of jurisdiction name occurs in,
     iso: unique identifier of the jurisdiction, usually an ISO code,
     gender: most common gender of the name in the jurisdiction (m = male, f = female),
     percent: percent of people wo bear the name with the aforementioned gender,
     sample: number of records denoting name-gender relationships the percent was calculated from
}

For example, in the above result for Kylie, the first result means: in The United States 100% of people with the name Kylie are female (f); and this was calculated from 6,029 records denoting the gender of people named Kylie.
