Decile cutpoints - inclusive or not?

I am using SPSS to analyze data by income decile across multiple years. Using SPSS, I get decile cut points. (For example, 10th percentile = $12,000)
When analyzing data within what I call "Decile 1," is there an accepted practice around including the 10th percentile value ($0 - $12,000) or not including it ($0-$11,999)?

  • Thanks, everyone. I found a different way to do this in SPSS, where the deciles are created automatically (under Transform > Rank). Although this makes analyzing the data much faster, i can't figure out what the actual cut-offs are. Anyone have any experience with this? Or know an SPSS whiz or resource?
