Finding the values behind encode

Hi All,

I am working with two rounds of survey data, that interviews individuals across different states (varname v024) in India. I want to append the datasets but there are a few issues with the encoded state names that I need to sort out.

For example in data from 2015-16

Code:

tab v024

                      state |      Freq.     Percent        Cum.
----------------------------+-----------------------------------
andaman and nicobar islands |      2,811        0.40        0.40
             andhra pradesh |     10,428        1.49        1.89
          arunachal pradesh |     14,294        2.04        3.94
                      assam |     28,447        4.07        8.00
                      bihar |     45,812        6.55       14.55
                 chandigarh |        746        0.11       14.65
               chhattisgarh |     25,172        3.60       18.25
   --------------------------------------------------------------

Here for example the state andhra pradesh is encoded with value 2.

In the data from 2005-06, however, label names and values change:

Code:

 tab v024

                 state |      Freq.     Percent        Cum.

        [ka] karnataka |      6,008        4.83       89.59
              [go] goa |      3,464        2.78       92.37
           [ke] kerala |      3,566        2.87       95.24
       [tn] tamil nadu |      5,919        4.76      100.00
-----------------------+-----------------------------------
                 Total |    124,385      100.00

And the same state andhra pradesh now has label [ap] andhra pradesh with value equal to 28.

I thought to fix this I could instead generate a new variable called state, replace values and define labels to match 2015-16, and then append the two, dataset after creating a variable called state in 2015-16.

Code:

gen state =.
replace state = 2 if v024 == 28
replace state = 3 if v024 == 12
replace state = 4 if v024 == 18

label define 2 "andhra pradesh"  3 "arunachal pradesh" 4 "assam"

Else, appending without these changes result in the wrong states being matched based on the encoded value.

My question now is, given the rather large number of observations,how do I find the corresponding value behind each label without having to scroll through the data browser ie 1 - andaman and nicobar islands, 2- andhra pradesh 3 - arunachal pradesh etc? Also does the aforementioned method seem like the most efficient way to accomplish the correct append?

Thanks a lot!

Best,
Lori
