## Data Tables: Hemoglobin, Hematocrit, and Socio-economic Data - Massachusetts
### Overview
The image contains three data tables presenting results from a National Nutrition Survey conducted in Massachusetts. The first table details hemoglobin levels, the second hematocrit levels, and the third provides general socio-economic data. All data is categorized by age and sex (Males/Females).
### Components/Axes
The tables are structured with 'Age' as the primary category on the left column. Within each age group, data is further divided into 'Def.' (Deficient), 'Low', and 'Total Unsatisfactory' levels. The tables are separated by descriptive headers indicating the measured variable (Hemoglobin, Hematocrit) and the survey source (National Nutrition Survey). The final table presents socio-economic indicators without age/sex categorization.

* Females: Def. = 0.5, Low = 3.8, Total Unsatisfactory = 4.3
**3. General Socio-economic Data - Massachusetts**
* **Header:** "General Socio-economic data – Massachusetts"
* Total number of persons examined: 4,568
* Mean family size: 5.31
* Mean income: $ per annum: 6,500
* Mean poverty index ratio: 2.29
* % of families below poverty index ratio of 1.00: 19.5

### Key Observations
* The 'Total Unsatisfactory' levels generally increase with age for both hemoglobin and hematocrit, particularly in males.
* In both hemoglobin and hematocrit data, the 'Def.' levels are consistently low across all age groups, especially in females.
* The hematocrit data shows a significantly higher 'Total Unsatisfactory' rate for males aged 60+ (20.0%) compared to other groups.
* Nearly 20% of families in Massachusetts were below the poverty index ratio of 1.00, suggesting a substantial portion of the population faced economic hardship.
### Interpretation
The data suggests potential nutritional deficiencies, specifically related to iron (hemoglobin) and red blood cell production (hematocrit), within the Massachusetts population surveyed. The higher rates of unsatisfactory levels in older males could indicate age-related physiological changes or dietary factors. The socio-economic data provides context, indicating that a significant percentage of families lived below the poverty line, which could contribute to nutritional deficiencies. The ICNND guidelines referenced suggest these findings were evaluated against international standards for nutritional assessment. The source link points to a repository of industry documents, potentially indicating the data was collected or analyzed in relation to food or health-related industries. The data provides a snapshot of the nutritional and economic status of a population in Massachusetts during the time of the survey.
