Field Names Criteria
07 Date of Visit On Annual PedNSS Record Volume and Data Quality report, month and day values should be evenly distributed (quantity of values for Month should be total months/12 + 20%;  quantity of values for Day should be values for total days/30 + 20%.
09 Date of Birth On Annual PedNSS Record Volume and Data Quality report, month and day values should be evenly distributed (quantity of values for Month should be total months/12 + 20%;  quantity of values for Day should be values for total days/30 + 20%.
10 Sex  Values for code 1 (male) < 48% or > 56%.
14 Household Size > 20% of values > 6.  National distribution: 5% of values fall outside this cutoff.
15 Monthly Household Income > 20% of values > 2100.   National distribution:  5% of values fall above this cutoff.  Sum of records with values 0000-0900 > 80% of all records with values 0000-8000. 
16 Migrant Status Values for code 2 not greater than values for code 1.
21 Birthweight—English > 20% of values <04 (pounds), 14 (ounces) or > 20% of values > 09 (pounds),  02 (ounces).  National distribution:  5% of values are outside of each of these cutoffs.  1,2
22 Birthweight—Metric > 20% of values <2216 (grams)  or > 20% of values >4147 (grams).
National distribution:  5% of values are outside each of these cutoffs.  1,2
27 Date of Height/Weight Measure On annual data sets, Month and Day values should be evenly distributed (quantity of values for Month should be total records/12 + 20%;  quantity of values for Day should be total records/30 + 20%)
28 Hemoglobin     > 20% of values are <10.3 (g/dL) or >20% of values >14.0 (g/dL).   National distribution: 5% of values are outside each of these cutoffs. Digital preference: >30% of Hb values fall on the whole or half integer  (e.g. 11.0, 11.5,  12.0, 12.5)  (expected prevalence:  20%). 2,3
29 Hematocrit      > 20% of values are <31.7 (%) or >20 % of values > 41.3 (%).
National distribution:  5% of values are outside each of these cutoffs. 2,3
30 Date of Hemoglobin/Hematocrit Measure On annual data sets, Month and Day values should be evenly distributed (quantity of values for Month should be total records/12 + 20%;  quantity of values for Day should be total records/30 + 20%)3

Records for children ages < 12 months included in analysis.
33 Length of Time Breastfed Values for code 01 not greater than values for code 02 not greater than values for code 03.
Sum of records with codes 08, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48 exceeds sum of other codes from 04-52. 4
