What does "1 + Other Micronesian" race variable mean?

USA

I notice when I pull data about Micronesians in Hawaii on American Fact Finder, I can select ACS data for those who “Micronesian alone or in any combination.” When I use IPUMS to look at ACS data (2018 pooled 5 year), the detailed race variable is “1 + Other Micronesian Races.”

What does “1 + Other Micronesian Races” mean? Is this equivalent to “Micronesian alone or in any combination?”

Although the detailed RACE codes available in IPUMS USA are not always exactly equivalent to the detailed codes available on American Fact Finder, these response categories are equivalent.
