- Data to be listed
Chose all fields to be listed in the data set retrieved, since only fields ticked here will be displayed.
- Fields to be searched
After choosing the relevant field(s) from the drop-down lists, write your search criteria in the text box beneath.
The field on the upper left side is the primary key for sorting. Remember that fields are not presented in the
resulting list unless ticked in the boxes in (1).
Search criteria are as follows:
- Sex and birth year
In the bottom part of the screen you may optionally filter the resulting data set by sex or birth year. Both
the start year and the end year of a period must be specified, so a one year period is specified by entering
the same year twice.
- Chosing census year, provinces and municipalities
Trigger the search program by clicking one of the census year boxes. Optionally you may also filter the data
geographically by ticking one or more of the province names listed.
By ticking the municipality box, another
screen will be displayed for an optional filtering of the province(s) by a subset of municipalities.
- The resulting data set
The list of persons chosen is sorted alphabetically by the first search criterion selected. By clicking the
blue house icon , the program displays all the persons inhabiting a farm or other domicile, together with
data about the place of living.
- Domicile data set
In the list of persons living in the same house, flat etc, the head of each household is shown in boldface.
Italics denote absent persons.
Searching persons by birthplace by using municipality codes
This search method will result in a more well defined data set than searching place names, since the
problems of spelling variations and the use of farm names, village names in the census is eliminated.
For instance the information on birth place in the 1900 census contains more than 75000 different text
strings. For instance, searching for the code 4050 gives us the more than 50000 Swedes residing in
Kristiania (Oslo) in 1900, while searching for Sweden gives less than 6500 persons.
See the municipality codes for Norway and country codes for immigrants. Specifying one or
- The single code 1840 stands for Saltdal municipality in Nordland province, and only persons
born here will be listed.
The negation 1840- results in a search for all persons not having the birth place code 1840,
a negation thus being used to find all persons born outside a specific municipality. This can be used to
find all in-migrants to Saltdal if you simultaneously delimit the search to people living in Saltdal (cf
the geographic filter in the searching instruction).
A municipality code followe by an exclamation point excludes all persons living in the said
municipality, in this case resulting in a list of out-migrants from Saltdal. By combining with geographic
filtering, out-migrants to certain parts of Norway, for instance Nordland province can be listed.
The hyphen specifies a list of municipality codes. Since codes usually are arranged
topographically, a contiguous area within a province can be specified, in this case the municipalities
from Saltdal through Hamarøy in Nordland province. Because the list of codes is historically dynamic,
some of the municipalities specified may not exist in every census year.
By adding the exclamation point to example 4, the resulting list is limited to out-migrants
from the municipalities Saltdal through Hamarøy.
The three final examples show alternative ways of specifying contiguous municipality codes
by using the greater than sign (>), less than sign (<) and the asterisk (*) or a combination these signs.
Even though placed behind the code for technical reasons, the sign is interpreted as if placed before the
code. 1840< lists persons born in municipalities with a birth place code below 1840, that is south of Saltdal.
1840> lists persons born in municipalities with a code higher than 1840, for practical purposes persons born
north of Saltdal. By truncating the code with the asterisk (18*), we find persons born in municipalities
whose codes start with the specified digits, in this case Nordland province.
Good luck with your more closely specified searching!
