ANALYZING DATASETS

The following information provides for hypothetical relationships created by examining the data used in the GIS Infectious Disease (Autism) Prototype

This analysis does not draw about definite conclusions

This analysis examines different dataset trends and patterns individually and some datasets are examined with one another

User can use similar methods and/or different datasets to cross examine and compare information; drawing their own conclusions

LAYER ANALYSIS

Data layers based on the high, medium and low levels of autism prevalence reported in New Jersey, New York and Florida with the US Census’ Median Household Income and number of hospitals in the three states

LAYER ANALYSISNew Jersey - most areas shaded green,- majority of the area has a relatively

higher household income when compared with other states

- Relative to the household income (within each state based on the median value for that particular state) most hospital locations are clustered together closest to New York City in an area where the household income ranges from $24,000 to more than $82,000

- household income relative to hospital location shows that the lowest income is in an area surrounded by higher income

- Compare to population here!

LAYER ANALYSIS

Hospitals in New York are located mainly in areas with a household income of $24,001 to $39,000. However, in New York City more hospitals are found in areas with a household income over $68,001

LAYER ANALYSIS

Florida hospitals are located mainly in areas with a household income of $24,001 to $39,000

LAYER ANALYSIS Diversity in the three states and the diversity index of

Autism patients by ethnicity can be overlapped to examine patterns.

The first part of the chart looks at the “Prevalence of Diversity” and examines the prevalence of autism for the four years represented and categorizes them by different ethnicities.

The second portion of the chart comes from the US Census (http://quickfacts.census.gov/qfd/states/36000.html) and examines as a whole the diversity of the population for each state for a combined numbers of years in which the US Census measures change.

This is intended to examine patterns between the population diversity as a whole and the prevalence of autism as a part of the whole, relatively over a particular time that reflects change in diversity.

LAYER ANALYSIS

The relationship between the total diversity in each state versus the autism prevalence based on diversity within that same state. We can see the relationship in the ratio

comparison between the two variables. For instance, can this mean that if a state with a

particular diversity appears greater, then does the data also shows a greater prevalence of autism?

Will this suggest that most white people show greater autism prevalence then Asian people? And not because autism targets white people more but because there is a greater population?

LAYER ANALYSIS Maps below show the diversity index within each state examined. In New York and New

Jersey we see a relatively higher diversity index closest to New York City; whereas in Florida the diversity index seems to be more spread out across the state

LAYER ANALYSIS Prevalence of autism Vs. Population under 18 years old Vs. Population per household Vs.

Overall population density (Comparing four layers in one table view and converting that to map view)

Table 3 shows all three states have relatively same percentage of population under 18 years old. We can also see that based on total population New York has the highest population density (also known as the population count) and the highest number of autism prevalence. Yet although New York has populations almost double the density of New Jersey; the rate at which autism prevalence increases in New Jersey is greater than that of New York

Total population density

LAYER ANALYSIS

Population Vs. Hospital Locations (New York, New Jersey & Florida)

The next 6 slides explore the relationship in the three states based on Population density of both overall population and Population under 18 years of age Versus Hospital Locations

This examination will be helpful in analyzing the proximity of hospitals in areas ranging from most dense to least densely populated

LAYER ANALYSIS Prevalence of Autism Vs. Median home value Vs. Hospital locations

Median home value in USA is $186,200. Let’s examine the relationship hypothetically between the value of a home and how conveniently a hospital is located near that home.

LAYER ANALYSIS

New York and New Jersey home values closer to NYC seem to be the highest, above USA average, whereas although Florida contains a few areas with relatively high home values, the overall home value in Florida is the lowest. Also hospitals appear to be conveniently located near areas with high home values; possibly making it convenient for families to get immunization, medical care, routine check-ups as well as emergency care.
