BUILT FROM VCF0101 (EXCEPT 1954). SEE NOTES VCF0101. The 1948 and 1954 NES age variables were present as age groups which do not allow simple recoding.

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. 1. 1975 - Present 2. 1959 - 1974 3. 1943 - 1958 4. 1927 - 1942 5. 1911 - 1926 6. 1895 - 1910 7.
