[Review] Column and data inconsistency across years

[sehansi-9]

For multi year comparison and visualisation purposes, the column names across the years should be consistent.

All columns available for a dataset name across the years should be reviewed carefully and a common column format for each should be decided to avoid duplications.

Example: Column Name Variations

• Number of arrivals
• No. of arrivals
• arrivals
• number

All of the above should be converted to one common format.

Country Name Inconsistencies

For country names, one name should be decided for countries with multiple names/definitions.

Example

• Republic of Zimbabwe
• Zimbabwe
