The Genealogists Society of Ireland is trying to discover which Irish
surnames occur most frequently in the counties of Munster. In order to
obtain this information they have persuaded the government to make available
to them some of the information from the most recent census. Unfortunately,
since there is no fee involved, the government can only make available
a standard file covering the entire 26 counties.
Comma delimited or comma separated values (CSV), is a file format widely
used in the computing industry. It allows data to be transferred between
applications with incompatible file formats (Excel, for example, can save
its spreadsheets in this form). CSV files consist of free format, variable
length records where the fields are separated by commas and do not occupy
specific areas. Before the records in a CSV format file can be processed
they must be unpacked into individual fields .
The Census Population File provided by the government has a CSV-like
format. Each record contains a census number, a surname and a county
name. The fields are separated from one another by commas. The file
For your guidance;
the census number is 7 digits in size
the surname is a maximum of 20 characters in size
the county name is a maximum of 9 characters in size.
You will need to sort the file on ascending Surname within ascending
County name. Use an Input Procedure to unpack the records and get rid
of any non-Munster records. Use a table to find the top ten surnames
in each county.
