Cleaning up the Data

Make all headers lowercase and remove spaces

By looking at the structure one can determine there are 44 variables in this dataset. By using “summary(hatecrimes)”, you can then decide which of the hatecrimes to focus on.

names(hatecrimes) <- tolower(names(hatecrimes))
names(hatecrimes) <- gsub(" ","",names(hatecrimes))
str(hatecrimes)

Selecting certain hatecrimes

Decided to only look at the hatecrimes types with a max number of 9 or more. By doing this, only the most prominent types of hatecrimes are examined.

hatecrimes2 <- hatecrimes %>%

Using Facet_Wrap

Facet_wrap allows you to plot all the variables together for comparison

Use the “tidyr” package to convert the dataset from wide to long with the command “gather”. This will take each column’s hatecrime type and combine them into one column named “id”. Each cell count will then go into the new column, “crimecount”.

hatecrimeslong <- hatecrimes2 %>% 
  tidyr::gather("id", "crimecount", 3:10) 

hatecrimesplot <-hatecrimeslong %>% 
  ggplot(., aes(year, crimecount))+
  geom_point()+
  aes(color = id)+
  facet_wrap(~id)
hatecrimesplot

Looking Deeper into Hatecrimes Against Blacks, Gay Males, and Jews

By looking at the facet_wrap, it can be determined that the anti-Black, anti-gay males, and anti-Jewish categories seem to have highest rates. Filter out just for those 3 crimes using “filter”.

hatenew <- hatecrimeslong %>%
  filter( id== "anti-black" | id == "anti-jewish" | id == "anti-gaymale")%>%
  group_by(year, county) %>%
  arrange(desc(crimecount))
hatenew
## # A tibble: 1,269 x 4
## # Groups:   year, county [277]
##    county   year id          crimecount
##    <chr>   <dbl> <chr>            <dbl>
##  1 Kings    2012 anti-jewish         82
##  2 Kings    2016 anti-jewish         51
##  3 Suffolk  2014 anti-jewish         48
##  4 Suffolk  2012 anti-jewish         48
##  5 Kings    2011 anti-jewish         44
##  6 Kings    2013 anti-jewish         41
##  7 Kings    2010 anti-jewish         39
##  8 Nassau   2011 anti-jewish         38
##  9 Suffolk  2013 anti-jewish         37
## 10 Nassau   2016 anti-jewish         36
## # ... with 1,259 more rows

Plotting These 3 Types of Hatecrimes Together

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 = id),
      position = "dodge", stat = "identity") +
  ggtitle("Hate Crime Type in NY Counties Between 2010-2016") +
  theme(plot.title = element_text(hjust = 0.50)) +
  ylab("Number of Hate Crime Incidents") + 
  labs(fill = "Hate Crime Type")
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?

Bargraphs can be made by counties rather than years

plot3 <- hatenew %>%
  ggplot() +
  geom_bar(aes(x=county, y=crimecount, fill = id),
      position = "dodge", stat = "identity") +
  ggtitle("Hate Crime Type in NY Counties Between 2010-2016") +
  theme(plot.title = element_text(hjust = 0.50)) +
  ylab("Number of Hate Crime Incidents") + 
  labs(fill = "Hate Crime Type")
plot3

Clearly there are way too many counties for the x axis to be even legible

Fix for the Number Counties

Only the 5 counties with the highest number of incidents can be observed. - Use “group_by(county, year)” to group the rows by counties. - Use “summarize(sum = sum(crimecount))” obtain the total sum of incidents by county - Use “arrange(desc(sum))” to arrange that sum by counties in descending order

counties <- hatenew %>%
  group_by(county, year)%>%
  summarize(sum = sum(crimecount)) %>%
  arrange(desc(sum)) 
## `summarise()` has grouped output by 'county'. You can override using the `.groups` argument.
counties
## # A tibble: 277 x 3
## # Groups:   county [60]
##    county    year   sum
##    <chr>    <dbl> <dbl>
##  1 Kings     2012   136
##  2 Kings     2010   110
##  3 Kings     2016   101
##  4 Kings     2013    96
##  5 Kings     2014    94
##  6 Kings     2015    90
##  7 Kings     2011    86
##  8 New York  2016    86
##  9 Suffolk   2012    83
## 10 New York  2013    75
## # ... with 267 more rows

Lastly, create a bargraph for only the 5 counties with the highest hatecrimes in 2012. The command “labs()” is efficient as it helps create the title, subtitle, y-axis label, and legend title, all in one command.

plot4 <- hatenew %>%
  filter(county =="Kings" | county =="New York" | county == "Suffolk" | county == "Nassau" | county == "Queens") %>%
  ggplot() +
  geom_bar(aes(x=county, y=crimecount, fill = id),
      position = "dodge", stat = "identity") +
  labs(ylab = "Number of Hate Crime Incidents",
    title = "5 Counties in NY with Highest Incidents of Hate Crimes",
    subtitle = "Between 2010-2016",
    fill = "Hate Crime Type") +
  theme(plot.title = element_text(hjust = 0.50))
plot4

How Would Calculations be Affected by Looking at Hatecrimes in Counties Per Year by Population Densities?

setwd("C:/Users/Justin Park/Desktop/DATASETS")
nypop <- read_csv("newyorkpopulation.csv")

Clean the County Name to Match the Previous Dataset

Rename the variable “Geography” as “county” so that it matches in the other dataset

nypop$Geography <- gsub(" , New York", "", nypop$Geography)
nypop$Geography <- gsub("County", "", nypop$Geography)
nypoplong <- nypop %>%
  rename(county = Geography) %>%
  gather("year", "population", 2:8) 
nypoplong$year <- as.double(nypoplong$year)
head(nypoplong)

Focusing on 2012

Since 2012 has the highest number of hatecrimes the population of counties in 2012 will be observed

Clean the nypoplong12 variable, county, so that matches the counties12 variable by Cutting off the “, New York” portion of the county listing

nypoplong12 <- nypoplong %>%
  filter(year == 2012) %>%
  arrange(desc(population)) %>%
  head(10)
nypoplong12$county<-gsub(" , New York","",nypoplong12$county)
nypoplong12
## # A tibble: 10 x 3
##    county       year population
##    <chr>       <dbl>      <dbl>

##  9 Monroe       2012     748947
## 10 Richmond     2012     470978

Comparing this to the previous found data in number of hatecrimes: Kings 713 New York 459 Suffolk 360 Nassau 298 Queens 235

A similarity can be seen between the two datasets

Filter hate crimes just for 2012 as well

The highest rate of hatecrimes in 2012 happened in Suffolk (5.54). Clearly this does not correspond with the previously determined data of highest populated counties (respectively: Kings, Queens, New York, Suffolk, Bronx, and Nassau)

The crime rate does not correspond directly but it is similar to that of the counties.
