Loop through and concat spatial files with Geopandas - dataframe

Question

I've been trying to batch process a series of .geojson files for demographic census tract data into into one output GeoDataFrame. All the inputs have the same file shape, shared index/label and geometry columns. For example:
Table 1:
Geo
Businesses
Geometry
Census Tract 1
5
Polygon(x,y)
Census Tract 2
6
Polygon(x,y)
Table 2:
Geo
Employees
Geometry
Census Tract 1
100
Polygon(x,y)
Census Tract 2
2
Polygon(x,y)
Table 3:
Geo
Loans
Geometry
Census Tract 1
94
Polygon(x,y)
Census Tract 2
3
Polygon(x,y)
...and so on.
I expect to get an output like this:
Geo
Businesses
Employees
Loans
Geometry
Census Tract 1
5
100
94
Polygon(x,y)
Census Tract 2
6
2
3
Polygon(x,y)
I've had scucess doing this for .csv and .xlxs files, but I have not been able to successfully with geopandas. So far my workflow has been the below:
First, I set point the .geojson files I want in my directory:
# point to files in data_path directory so we can loop them all
files = os.listdir(inputs_path)
files_mo_geojson = [f for f in files if f.endswith('MO.geojson')
#view
print(files_mo_geojson)
['SBALoans_CensusTract_MO.geojson',
'Businesses_5_9_Employees_CensusTract_MO.geojson',
'Businesses_Under50_Employees_CensusTract_MO.geojson',
'Businesses_1_4_Employees_CensusTract_MO.geojson']
then i make an empty geodataframe
gdf_mo = geopandas.GeoDataFrame()
and try various methods of getting the output desired
#this results in have teh index duplicated for each time a new geodataframe is adhered
for file in files_mo_geojson:
data = geopandas.read_file(inputs_path/file)
gdf_mo = gdf_mo.append(data,ignore_index=True)
or
#this results in only the first geodataframe being read in
for file in files_mo_geojson:
data = geopandas.read_file(inputs_path/file)
geopandas.GeoDataFrame(pandas.concat([gdf_mo,data], ignore_index=True))
or
#this results in all geodataframes being read in but only the first onen listed retaining values
for file in files_mo_geojson:
data = geopandas.read_file(inputs_path/file)
gdf_mo = gdf_mo.append(data,ignore_index=True).dissolve(by='label',aggfunc='sum')
or
#this results in only the first geodataframe being read in
for file in files_mo_geojson:
data = geopandas.read_file(inputs_path/file)
gdf_mo = geopandas.GeoDataFrame(gdf_mo.merge(data,left_on='geometry',right_on='geometry'))
