Ethnicities and genders
: Martin Holmes
Minutes: 90
Some of the earlier censuses have data columns where people of
various ethnicities co-habiting with the householder are listed;
I’ve modelled these using personGrp elements which
have @ethnicity, @gender and @value (for the count) attributes.
For the census row principal, there is a value for Sex
in the
database, but it’s a mess; it should contain only M
or F
,
but for some reason there are records which contain 0
,
9
, S
, D
, and !
. Most of these are
errors but some may be survivals from the old Access db, so I’ve
written to PD to see if he has any insights. I’ll probably end up
using the old ISO standard 0,1,2,9 for this, since it covers our
needs and there’s no way to learn more.
