Visualize these counts as a bar graph

ggplot(hatecrimes, aes(x = biasmotivedescription))+
  geom_bar()

Use inclusion/exclusion criteria to filter

bias_count |>
  head(10) |>
  ggplot(aes(x=biasmotivedescription, y = n)) +
  geom_col()

Arrange the bars according to height and rotate

bias_count |>
  head(10) |>
  ggplot(aes(x=reorder(biasmotivedescription, n), y = n)) +
  geom_col() +
  coord_flip()

Add title, caption for the data source, and x-axis label

  ggplot(aes(x=reorder(biasmotivedescription, n), y = n)) +
  geom_col() +

Finally add color and change the theme

Add annotations for counts and remove the x-axis values

Plot these three types of hate crimes together

ggplot(data = hate2) +
  geom_bar(aes(x=complaintyearnumber, y=n, fill = biasmotivedescription),
      position = "dodge", stat = "identity") +

What about the counties?

ggplot(data = hate2) +
  geom_bar(aes(x=county, y=n, fill = biasmotivedescription),
      position = "dodge", stat = "identity") +
  labs(fill = "Hate Crime Type",

       title = "Hate Crime Type in NY Counties Between 2010-2016",
       caption = "Source: NY State Division of Criminal Justice Services")

The highest counts

Put it all together with years and counties using “facet”

ggplot(data = hate2) +
  geom_bar(aes(x=complaintyearnumber, y=n, fill = biasmotivedescription),
      position = "dodge", stat = "identity") +
  facet_wrap(~county) +

       title = "Hate Crime Type in NY Counties Between 2010-2016",

How would calculations be affected by looking at hate crimes in counties per year by population densities?

One of the positives to this dataset is that it shows specific hate crime type/bias motives (Anti-Jewish, Anti-Gay, Anti-Asian, and Anti-Black). By including this and not just generalizing one variable as just “hate crimes,” it lets us see which specific communities are being targeted. Additionally, the dataset also provides where these specific hate crimes are happening. So being able to pinpoint the type and the location better tells us where support is most needed. It’s also critical information that can help leaders and citizens of neighborhoods to organize safety patrols and decide where city resources be established to these “hot spots”. Another positive to this dataset is how it is regularly updated and this short-term almost immediate data allows enforcement and citizens to react to spikes while they’re happening. While on the other hand, their data over the set of several years helps figure out long-term trends where enforcement and researchers can identify if these counties and overall, the city, is actually becoming safer over time or getting worse.

There are some negatives to this dataset, one of them being underreporting. This commonly reveals an apparent issue when it comes to hate crimes data. Many marginalized or undocumented communities may avoid reporting incidents due to fear of retaliation, language barriers, or mistrust of law enforcement. Consequently, the dataset likely represents only a fraction of actual hate crime incidents. This can ultimately misrepresent actual data, which can be dangerous in the long run because city funding and police resources are often tied directly to these numbers. The dataset does not explain any factors of underreporting that affects their data. This ties into another issue of what is considered a confirmed hate crime. In incidents where bias was likely present but couldn’t be legally proven to the Task Force’s standard, are excluded, which again can misrepresent the actual data, and those have trickling down consequences as well.

I am interested in how geography and socioeconomic factors intertwine with specific issues. One hypothetical study about this dataset that I would like to do at some future point is where these hate crimes are happening and explaining an aspect of “why” with socioeconomic factors. By pinpointing exactly which boroughs and precincts are seeing spikes, we can see where help is needed most. And by layering this dataset with other census data, such as income levels and education, we can further see the socioeconomic environment where these crimes occur. Another study I would be interested in with this dataset is comparing this city’s, New York, to other major U.S. cities’ hate crime data (such as Los Angeles and Philadelphia). This can reveal a lot of different information and insights including what are national versus local specific hate crimes and what are the trends associated with these data. Additionally, it can uncover and help identify what this dataset or other cities are missing in order to get a full picture.
