        The 1948 and 1954 NES age variables were present as age groups which  
        do not allow simple recoding.  An estimate was made to fit those      
        codes into the cohort categories.  The original age categories        
        were:                                                                 
           1948:  1.18-24; 2.25-34; 3.35-44; 4.45-54; 5.55-64; 6.65 and over. 
           1954:  1.21-24; 2.25-34; 3.35-44; 4.45-54; 5.55-64; 6.over 65.     
        The 1948 recode used was:  1=4, 2=5, 3-4=6, 5-6=7.                    
        The 1954 recode used was:  1=4, 2-3=5, 4-5=6, 6=7.
