Girls with a combination of surnames (Spanish and Mapuche), other surnames (neither Spanish nor Mapuche), and girls for whom at least one parent's surname was not known were excluded from the study.
However, if you are changing your name to a combination of surnames or to a new surname, they will require that the SSA verify your name change.
Our findings suggest that the combination of surname, sex and date of birth appears to be optimal using deterministic linkage.
The linkage rate between the population and Vital Statistics registries when using the combination of surname, sex and date of birth was 88.0%; the correct linkage rate was 96.9%.
In our study, a combination of surname, sex and date of birth has the highest linkage rate and second highest correct linkage rate.
The linkage rates might be increased taking the strategy of first matching records using unique identifiers, and then matching remaining records using a combination of surname, sex and date of birth.
Our results showed that among the three combinations using the four possible identifiers, the combination of surname, sex and date of birth is the optimal choice in achieving the best deterministic linkage.
In our study, we selected four common identifiers (surname, first name, sex, and date of birth) from a set of personal identifiers and composed three different combinations of four identifiers: (1) a combination of surname, sex and date of birth, (2) first name, sex, and date of birth, and (3) surname, first name, sex and date of birth.
Among the three combinations, the combination of surname, sex, and date of birth had the highest linkage rate of 88.0% and 93.1%, and the second highest correct linkage rate of 96.9% and 98.9% between the population registry and Vital Statistics registry, and between the hospital discharge data and Vital Statistics registry in 2001, respectively.
On the other hand, precision is slowly decreasing for more common names, see Figure 4(b), which becomes an issue when disambiguating very large databases, where certain combinations of surname plus first initial can result in initially undisambiguated clusters comprising around ten thousand publications.
He had emphatically got his mojo back, and a combination of his surname and Movember moustache made MoJo an inevitable nickname.
