📃 This article is Part 8 in a series on Identifying Electoral Fraud Using Trend Analysis.
We recommend reading these preceding articles in order to understand the context and terms used:
We discussed the zscore concept in Part 3: The Curious Case of the 2020 “Voting Rate” Blowouts.
The zscore gives us an indication of how far a value is from the mean, when measured in standard deviation units.
It allows us to normalize results across multiple datasets in order to compare them with one another.
💡 A Quick Refresher on ZScores:
A zscore of “0” would indicate the assessed value is equal to the mean of all the other values in the dataset.
A zscore of “2” would indicate the assessed value is 2 standard deviation units away from the mean.
When the values in a dataset follow a normal distribution, a zscore greater than 2.5 is rare.
If a dataset contained 100 values, we would only expect one value to have a zscore greater than 2.5.
A zscore greater than 3 is extremely unlikely. In fact, in a lot of data analysis and machine learning scenarios, a value with a zscore greater than 3 is considered an “outlier”. i.e. the value is removed from the analysis because it is considered so rare that it must be an “anomaly”. Let that sink in.
We can calculate zscores for all key parameters, discussed in the previous articles, which will allow us to compare the 2020 results with the previous 5 elections, to quickly identify the 2020 values that look unlikely.
The most important parameters are:
T/DR  Total Democrat votes divided by Democrat registrations 
DVI  Democrat Vote Increase (from previous election) 
RVI  Republican Vote Increase (from previous election) 
TI/TRI  Total Vote Increase divided by Total Registration Increase 
TV  Total Votes 
TR  Total Registrations 
Not all states provide registration data, so we can’t calculate the T/DR for all states. However we can calculate the DVI for every state, so we will look at the zDVI score first.
Looking at Democrat Vote Increases: The DVI ZScore (zDVI)
We calculated the DVI for all counties in all states, and then determined the zscore for each DVI in 2020 (in the zDVI column). We then filtered the list to only display the counties with a DVI zscore greater than 2.5.
💡 TIP:
A zscore of 2.5 will put the value in the 99% percentile. In other words we should only expect to see such values once in every 100 elections.
A zscore greater than 3 is extremely unlikely. (Remember, in many data analysis scenarios these values are considered so rare that they are called “outliers” and removed from the dataset.)
There are over 388 counties across 37 states that have a zDVI score greater than 2.5! So we had to display the images on their own page:
Show Full List of zDVI Values Greater than 2.5, By State
🤯 For comparison, if we compare the 2016 election results with the previous 4 elections, we only get five counties with a zDVI greater than 2.5. In 2020, there was suddenly 388!
Summary:
These are the states with the most counties with a zDVI score greater than 2.5:
 Texas has 73
 Georgia has 51
 Kansas has 27
 Washington has 22
 Oklahoma has 21
 Tennessee has 21
 Kentucky has 18
 Oregon has 17
 New York has 11
 California has 11
 Utah has 11
 Colorado has 10
 Arizona has 10
 South Carolina has 9
 Alabama has 9
 Florida has 7
 Virginia has 6
A state that is notably missing is Pennsylvania… which makes one wonder how much worse the states in the list above are!
Observations:
 A lot of the counties with a zDVI score greater than 2.5 are Republican strongholds. They have consistently voted Republican since (at least) the year 2000. Does it really make any sense that the Democrat Vote Increase (DVI) would set new records in 2020, in such counties?
 Whenever a county has a large zRVI (Republican) score it is often eclipsed by an even larger zDVI score, especially in the larger counties. (Coincidence?)
 The fact that so many counties across so many states have abnormally high zscore values is troubling (to say the least).
A Look at Democrat Voter Turnout Rates: The T/DR ZScore (zTDR)
As we have mentioned previously, we can only calculate the T/DR ratio (i.e the Democrat votes divided by the Democrat registrations), if a state provides registration data by party.
When we do have access to the registration data, we believe an “abnormal” T/DR value is the most powerful indicator of suspicious activity within a county.
There are over 331 counties across 17 states that have a zTDR score greater than 2.5, so again we had to display the images on their own page:
Show Full List of zTDR Values Greater than 2.5, By State
🤯 Again, for comparison, if we compare the 2016 election results with the previous four elections, we only get thirteen counties with a zTDR greater than 2.5. In 2020 it jumped to 331!
Summary:
These are the states with the most counties with a zTDR score greater than 2.5:
 North Carolina has 67
 Oklahoma has 49
 Florida has 34
 Louisiana has 33
 Pennsylvania has 24
 Oregon has 21
 Kentucky has 15
 Maryland has 10
 Massachusetts has 9
 Arizona has 7
Observations:
 What happened in Oklahoma, Oregon, Nebraska, Louisiana, Kentucky and North Carolina? All these counties are Republican strongholds!
 Many of the counties with high zTDR scores are different to the counties with high zDVI scores. This is concerning because that does not leave us with a lot of counties with low zscores.
 Only 17 states provide full registration data by party. Imagine how many more counties with zTDR values greater than 2.5 there would be, if we had registration data for all 50 states.
2016 Comparison
Here are the 17 counties that have either their zDVI or zTDR value greater than 2.5 at the 2016 election:
In 2020, the number of counties with either a zDVI or zTDR value greater than 2.5 ballooned to 647. (As we noted above, 388 counties have a zDVI greater than 2.5 and 331 counties have a zTDR greater than 2.5.)
Observations:
 It is remarkable that there is so little overlap between counties with large zDVI and zTDR values
 Unsurprisingly, many of the “anomalous” counties in 2016 are very large counties (based on the total votes shown in the “TV 20” column)
 Orange County, CA, voted Democrat for the first time in a long time in 2016, after a huge Democrat surge (and an even bigger surge in 2020)
 MiamiDade, FL, had a large Democrat surge in 2016, which then completely collapsed in 2020. What happened? Why such a big change of heart?
 Massachusetts has large counties with extremely unlikely zscores in 2016 😱, and even higher (much higher!) zscores in 2020. (Yes, that is a big give away 😉)
Full County Analysis by State
Here is the CSV file containing the complete analysis for ALL counties in ALL states.
You can use this CSV file to look at your county and compare it with other counties in your state.
Remember: any zscore, in any column, that is greater than 2.5 is suspicious and would warrant further investigation.
The table includes the following analyses:
 Winning Range analysis (Loc.20)
 Registration and Vote trend analysis (RVT category: NR and ND)
 2012 and 2016 Negative DVI value categorization (DVICat)
 DVI# for 2008 and 2020 (Comparing Obama’s results with Biden’s)
 Zscores of all key parameters
Summary
The zscore is an impartial measurement for classifying values within a dataset.
During a normal election we would only expect to find a handful of counties with high zscore values, above 2.5, like in 2016. Here’s the comparison again:
Election  Based on Democrat Vote Increase  Based on Democrat Turnout 

2016  5 counties over 2.5  13 counties over 2.5 
2020  388 counties over 2.5  331 counties over 2.5 
We only focused on the DVI and T/DR values in this article, however other important parameters, such as RVI, TR, and TV, all display troubling zscore values as well.
The 2020 election had hundreds of counties with extremely high zscore values. The quantity and magnitude of the zscores indicate the results are extremely unlikely.
(Just think of the odds that the same person would be struck by lightening 3 years in a row, at exactly the same location, on the same date, at exactly the same time, wearing exactly the same clothes, with Mars, Venus and Neptune being aligned, during a total solar eclipse, without a single cloud in the sky. Yes… extremely unlikely!)
These unlikely values are consistent with our other findings and point to the fact that more needs to be done to investigate the 2020 election.
The data speaks for itself.
At this stage of the analysis the evidence is overwhelming. We’d even venture to say that anyone refusing to take this seriously and allow independent audits of the election is either willfully blind or complicit. We call on all officials and state representatives to look openly and transparently at the results and allow the US public to verify that the election was run honestly and securely.
Stay tuned for our next article on Down Ballot Analysis, where we look at interesting statistical findings on how the Presidential race results compared to the other races in the same election.
