how to interpret the mean of a MCA analysis?

[Lewis Polo]

Hi how are you? I hope this email finds you well.

I've been building an index with the command MCA using categorical variables. I did all the process as shown below, the point is that I don't really know how to interpret the mean of the index (this is a wealth index including variables regarding dwelling and personal features).

I've read the help document of STATA, but I still confuse about that interpreting. I hope you can help me with this.
