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 quantitative variables, which are in columns 3 - 10. Note the command facet_wrap requires (~) before “victim_cat”.
Look deeper into crimes against blacks, gay males, and jewish people
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.

# ℹ 267 more rows
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

5 Queens 235
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
How would calculations be affected by looking at hate crimes in counties per year by population densities?
Bring in census data for populations of New York counties. These are estimates from the 2010 census.

Focus on 2012
Since 2012 had the highest counts of hate crimes, let’s look at the populations of the counties in 2012.
Clean the nypoplong12 variable, county, so that matches the counties12 variable by Cutting off the “, New York” portion of the county listing

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.
Recall the total hate crime counts:

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.
The categories used in the hate crimes data set were thorough and extensive, which theoretically should paint a richer picture. The downside is that the counties documented may not share the same level of thoroughness, which may contribute to an inaccurate picture. In fact, it is surprising that the categories aren’t already aggregated.
It might make for a more multifaceted story if other data is joined with the hate crimes dataset and the population data from the US census. Perhaps the census could be mined for more socioeconomic variables, such as the median household income of each county.
I would like to look into whether anything has changed about the way the FBI collects this data or states report this data in past six years or so. In particular I am curious if any changes correspond to changes in political administrations at the local, state, and national level.
I wonder if there is a way for victims to be allowed to appeal the classification of the crimes committed against them to be re-categorized as hate crimes. Even if the appeals are denied, it would allow for data to be collected on people who self-identify as victims of a hate crime. If that is too much to ask of local and state governments, there could be a mechanism for victims and whistle-blowers to report hate crimes directly to the FBI. This would at least catch data that is not collected when counties or states do not protect certain classes that the federal government recognizes (ant-LGBTQ crimes are the prime example of this). If there is a movement aiming to reform the way this data is collected, it is worth supporting.
I also wonder if software can be used to scan police report for keywords related to hate crimes. Schwencke notes there have been cases of swastikas being charged as mere vandalism. By searching for incidents of offensive imagery, reports of slurs used, and victims’ physical descriptions one might be able to locate more data points. It is worth looking into whether such software exists or has been proposed.
