Clean up the data:
Make all headers lowercase and remove spaces.
After cleaning up the variable names, look at the structure of the data. Since there are 44 variables in this dataset, you can use “summary” to decide which hate crimes to focus on. In the output of “summary”, look at the min/max values. Some have a max-vale of 1.

Convert from wide to long format
Look at each set of hate-crimes for each type for each year. Convert the dataset from wide to long with the pivot_longer function. It will take each column’s hate-crime type combine them all into one column called “victim_cat”. Then each cell count will go into the new column, “crimecount”.
Finally, we are only doing this for the quantitiative variables, which are in columns 3 - 10. Note the command facet_wrap requires (~) before “victim_cat”.
`geom_smooth()` using method = 'loess' and formula = 'y ~ x'
Look deeper into crimes against blacks, gay males, and jews
From the facet_wrap plot above, anti-black, anti-gay males, and anti-jewish categories seem to have highest rates of offenses reported. Filter out just for those 3 crimes.
Use the following commands to finalize your barplot: - position = “dodge” makes side-by-side bars, rather than stacked bars - stat = “identity” allows you to plot each set of bars for each year between 2010 and 2016 - ggtitle gives the plot a title - labs gives a title to the legend.
plot2 <- hatenew |>ggplot() +geom_bar(aes(x=year, y=crimecount, fill = victim_cat),position ="dodge", stat ="identity") +labs(fill ="Hate Crime Type",y ="Number of Hate Crime Incidents",title ="Hate Crime Type in NY Counties Between 2010-2016",caption ="Source: NY State Division of Criminal Justice Services")plot2
We can see that hate crimes against jews spiked in 2012. All other years were relatively consistent with a slight upward trend. There was also an upward trend in hate crimes against gay males. Finally, there appears to be a downward trend in hate crimes against blacks during this period.
What about the counties?
I have not dealt with the counties, but I think that is the next place to explore. I can make bar graphs by county instead of by year.
plot3 <- hatenew |>ggplot() +geom_bar(aes(x=county, y=crimecount, fill = victim_cat),position ="dodge", stat ="identity") +labs(fill ="Hate Crime Type",y ="Number of Hate Crime Incidents",title ="Hate Crime Type in NY Counties Between 2010-2016",caption ="Source: NY State Division of Criminal Justice Services")plot3
So many counties
There are too many counties for this plot to make sense, but maybe we can just look at the 5 counties with the highest number of incidents. - use “group_by” to group each row by counties - use summarize to get the total sum of incidents by county - use arrange(desc) to arrange those sums of total incidents by counties in descending order.
`summarise()` has grouped output by 'year'. You can override using the
`.groups` argument.

Top 5
To list the 5 counties with the highest total incidents, change group_by to: group_by(county), then use slice_max(order_by = sum, n=5) to list the 5 counties with highest total incidents.

Finally, create the barplot above, but only for the 5 counties in 2012 with the highest incidents of hate-crimes. The command “labs” is nice, because you can get a title, subtitle, y-axis label, and legend title, all in one command.
plot4 <- hatenew |>filter(county %in%c("Kings", "New York", "Suffolk", "Nassau", "Queens")) |>ggplot() +geom_bar(aes(x=county, y=crimecount, fill = victim_cat),position ="dodge", stat ="identity") +labs(y ="Number of Hate Crime Incidents",title ="5 Counties in NY with Highest Incidents of Hate Crimes",subtitle ="Between 2010-2016", fill ="Hate Crime Type",caption ="Source: NY State Division of Criminal Justice Services")plot4

Not surprisingly, 4/5 of the counties with the highest populations also were listed in the counties with the highest number of hate crimes. Only the Bronx, which has the fifth highest population is not in the list with the highest number of total hate crimes over the period from 2010 to 2016.

But the highest populated counties were: Kings (Brooklyn), Queens, New York, Suffolk (Long Island), Bronx, and Nassau. They do not correspond directly, though they are similar, to the counties with highest rates of hate crimes.
Important Findings: I wonder what the data would look like if there was a universally accepted requirement for this type of data collection.
The Bronx appears to have much lower than expected incvictim_catents of hate crimes relative to its population density in comparison to other NY counties.
In Kings County, NY (which is home to Brooklyn; according to Wikipedia, it is New York’s most populous borough and the second most densly populated county in the US) in 2012, there was a spike in hate crimes against jews.
All of these findings are corroborated in Hate Crime in New York State 2012 Annual Report: https://www.criminaljustice.ny.gov/crimnet/ojsa/hate-crime-in-nys-2012-annual-report.pdf
Homework Essay
One thing this dataset did quite well was distinguishing the different types of hate crimes that occurred in the state of New York in the years between 2010 - 2016 - in this case of this dataset, there were 38 separate categories recorded. Precisely-defined categories offer a more accurate picture of the variety of hate-motivated crimes that occur. After the original hate crimes dataset merged with the New York state population dataset and a rate of hates crimes per 100,000 people was calculated, I appreciated the inclusion of this variable. It placed the raw numbers of hate crimes recorded and placed it in the context of population size. A county may have a larger count of hate crimes, but a smaller population in general, making the concentration of hate crimes in that district of a greater number than in those counties that had both a high count of such acts and a larger population as well.
If I could explore two other aspects of this dataset, I would like to see how the annual rates for different types of hate crimes change over time. Can a spike in hate crimes with a specific target be related to news stories or historical events at the time? I would start by creating a faceted linear regression plot of the change in each type of hate crime over the years and then review these plots for interesting results. I would also like to explore the relationship, if there is any, between crimes against persons and crimes against property. Does one tend to occur at different times from the other? Does one tend to proceed or follow the other? For each type of hate crime that is recorded I would create a density ridge plot comparing the change in recorded incidents over the years in the form of both crimes against persons and property crimes to see if, and when, such patterns occurred.
One way I would like to follow up on this data set is to see if a catalyst can be found for these spikes. For example, an extraordinary spike in hate crimes against Jews was observed in 2012. Was there a local, national, or international incident that precipitated this hike? Knowing that this data is incomplete, another way I’d like to follow up with this dataset is to research why hate crimes are so often undercounted. Is the lack of resources or political will to do so on either the state or local level? Are some demographics targeted by hate crimes less likely to feel safe reporting hate crimes perpetrated against them to law enforcement, or have a lack of trust in law enforcement that would discourage them from reporting these offenses? I would love to explore these possibilities and look into others that have been proposed to get a more complete picture of hate crimes in New York State than that offered by the dataset alone.
