Hello. I wrote a similar application for my church, so I understand a bit of what you are asking for.
My first question is "have you evaluated the need for all the information you want to store?"
Here's why I ask:

The dates for inactive, received, and reinstated may have multiple instances.

Is that worth entering and maintaining? Will that data be useful, or even
used at some point?
In any case, normalization is one of those things that is useful, but only if you don't take it too far (I can already feel somebody's glare at my words!).
We opted to have a record for each person, and with that person was information that was specific to them (anniversaries, birthday, cell phone, emails, etc.). We only worried about their current status and the date they reached that status. One way of maintaining history without getting into cascading records is to maintain the current status and the date in fields, and keep a running log in a memo field. Each time a status changes, add the date and change to the log, and update the fields with the current status. This way the history is there when you need it, but not particularly easy to report on. If turnover is a concern, include a field that increments each time the status changes so it keeps count.
We opted to have a second set of records for "households". Each household has a street address, a land line, location (a generalized descriptor of the town but a distinct grouping). The primary purpose of a "household" was to collect people together into family groups with a common address. We found it more efficient to work with families since most of the time, updates to one member of a household applied to all members.
Then, we used a third table to manage who is in each household - kinda like creating a single level bill of materials. One of the people inserted into a household was designated as the "head" (the name that appears on address labels to the family and on many of the reports). Also, a string was included that contained the first name of each person in a single field (just to make some of the reporting easier - it was updated each time a person was added or removed from a house).
Now, when it comes to keeping attendance, there are several approaches. We track attendance by person, but the front end has us entering it by household, then person. This allows us to maintain attendance as people move (a child grows and leaves the house and starts their own house, or two people get married and move in together).
We also used a simple ranking system to identify each family as "regular attender", "occasional attender" and "non attender". When an event (such as a Sunday service) is created and then selected for attendance entry, the families (households) are divided into 3 lists. When you select a family, it moves to the attended list and is removed from the original list (for that event) and the members of the family appear on a list off to the side along with another of other fields (prayer requests, notes, etc.) we maintain regarding that family at that event. If a member happened to be absent, we unselect them in that list. Generally, by the end of attendance entry, most of the regular attenders list is empty (they are in the attended list) and maybe three quarters of the middle list is empty.
So, to summarize an answer to your question:
1 table for each person and information specific to a person (try to avoid "one-to-many" type pieces of data, although a few, such as multiple email addresses, are fine).
1 table for each household.
1 table to associate people into a household.
1 table to add events to.
1 table to add people to those events along with other relevant information.
Also, I suggest not separately tracking the dates of membership as they change, but if it makes sense for your organization, then 1 table to manage the status change history (still keep the current status in the person table just to simplify reporting).
Hope this helps
