Migration Table

Have a look at this: http://wazimap.co.za/profiles/ward-79800060/

According to the table - only 50.1% were born in South Africa. That's crazy. When you look at the data, it turns out that 22% are not applicable. When calculating this figure, I think that it would make more sense to take the N/As out of the equation. What do you think?

I'm not sure what 'not applicable' means in this context. Here's what the official docs say, and they don't mention not applicable. We need to ask Stats SA.

This question was asked to everyone who was part of the household. The respondents were asked to indicate the province in which they were born. If born outside South Africa, category 10 (Outside South Africa) was used. For elderly persons, it was difficult to define the place according to the current provincial divisions. The enumerators were instructed to ask for the names of the place where the person was born and then locate that place in one of the present provinces (e.g. born in Ciskei, record 02 was used for Eastern Cape).

All persons in households and transients

Final code list
01 = Western Cape 02 = Eastern Cape 03 = Northern Cape 04 = Free State
05 = KwaZulu-Natal 06 = North West
07 = Gauteng
08 = Mpumalanga 09 = Limpopo
10 = Outside South Africa 11 = Do not know
99 = Unspecified

This number isn't consistently high, it's only in a few areas. My understanding is that it means outside of SA.

Here's the map for wards in Jhb: http://wazimap.co.za/data/map/?table=PROVINCEOFBIRTH&geo_ids=ward|municipality-JHB&primary_geo_id=ward-79800060#column|Not%20applicable,sumlev|ward
