Annual Demographic Survey (March Supplement)

DIFFERENCES BETWEEN THE MARCH 1998 AND MARCH 1999 ANNUAL DEMOGRAPHIC FILES

  1. Item Description Change: The item PEINUSYR (location 731 on the person's record) has a revised description of value = 15. This value stands for 1996-1999.

  2. New (Revised) Items: Starting this year, topcoding was required for all non-earnings income fields that were not government program related. Section 3 lists the income sources and the revised topcodes. There are 14 topcode flags new to this year's person record, reflecting any topcoding to its corresponding income source field. The new flags, in columns 837 - 849, are: TSURVAL1, TSURVAL2, TDISVAL1, TDISVAL2, TRETVAL1, TRETVAL2, TINT-VAL, TDIV-VAL, TRNT-VAL, TED-VAL, TCSP-VAL, TALM-VAL, and TFIN-VAL. The flag TOI-VAL is in column 578.

    3. Item H-YEAR, year of survey, has changed in location and in size. It is now located in column 14 of the household record, and occupies 4 columns instead of only one.

  3. New Income Topcodes: This year, topcoding was required for all non-earnings income fields that were not government program related. The table below lists the topcodes applied to each of these 14 income fields newly subject to topcoding. The values subject to topcoding were replaced with the average amount across all topcoded values for that income source. These replacement averages are also listed.

    OI-VAL              25,000                 44,265

    The data after topcoding were used to create all combined income recodes on the file.

  4. Revised Topcodes: As was the case in previous years, the four basic earnings items were subject to topcoding again this year. The same topcodes as used in 1998 were used again (see the chart #1 below). We also replaced all topcoded values with the average amount across all topcoded records. Chart #2 below provides these average amounts for the 12 socioeconomic cells within which we computed these averages. Cells with a ---- did not have any topcoded records. Cells with an * did not contain at least 5 topcoded records and were collapsed together.
