I am starting the project and I get confused when I try to understand the meaning of
column that was given in the adult-training.csv. There is a column name,fnlwgt, that
represents final weight, which is the number of units in the target population that
the responding unit represents.
All I want to ask is: Is this "fnlwgt" like a id of a units in the target population.
Thanks for your time xD
Please correct me if I'm wrong but I believe that the data was used originally for machine learning training and the final weight column just shows how much the row shifted future decisions for their trained AI.
I doubt it would be a factor in business queries and is not a unique identifier.
